שלום לכולם, אני סטודנט בשנה ד

שלום לכולם, אני סטודנט בשנה ד' ויש לי שאלה .
אשמח לעזרה מכל מי שיש ביכולתו לעזור.
אז ככה - אני מבצע אנליזה מודלית למבנה רב קומות שאינו סדיר בתוכנת strap.
בניתי מודל מרחבי בstrap (הערת ביניים - המודל נבנה עם פונקציית submodel - מומלצת מאוד) - קירות, עמודים, תקרות וכו', המבנה נפתר וקיבלתי תוצאות. עד כאן אין בעיות.
השבוע רציתי לבנות מודל שונה נוסף בסטרפ ע"מ לאשר את התוצאות שהתקבלו - הרעיון היה לבנות מוט זיזי עבור כל גרעין בבניין ו"להעניק" לכל מוט את תכונות הגרעין - מומנט אינרציה (I) , שטח (A), מומנט התנגדות לפיתול (J) והיקף. המוטות הזיזים שמייצגים את הגרעינים מוקמו בצורה מרחבית במודל במרכזי הכובד של כל גרעין.
בנוסף בניתי עוד מוט זיזי שמטרתו היא לדמות את מרכז המסה כך שכל נק' רלוונטית בו מועמסת במשקל הקומתי שחושב ידנית, מוט זה קיבל חתך קטן בכדי לא להוות גורם קשיח במודל והוא מוקם במרכז המסה הקומתי.
בנוסף דאגתי כמובן לבצע rigid links בין כל קומות המבנה (נודים במישור X1-X2 עם גובה X3 זהה).
פתרתי את המודל והתוצאות שהתקבלו שונות מאוד. ברור לי שהן לא ייצאו זהות אך הן כ"כ שונות שמשהו במודל לדעתי אינו תקין. שכחתי לציין שזו פעם ראשונה שאני מנסה לבצע אנליזה מודאלית של מבנה ע"י זיזים בלבד.
אני אשמח אם למישהו יש הערה/הארה לגבי המודל ואם למישהו יש הסבר מדוע יש שוני כזה רב...
תודה

Shellfish similar to oysters and clams are glorious

sources of zinc, selenium, and omega-3 fatty acids, all of which can support

optimum testosterone levels. What’s extra, fatty fish

are good sources of zinc, vitamin D, and protein —

vitamins which might be important for sustaining healthy testosterone levels.

Ginger consumption has been linked to enhanced testosterone production, particularly among males with oxidative stress situations.

Zinc is a vital mineral for both men and women as a result

of it'll assist the body preserve an enough degree of hormones and enzymes, that are essential for

bodily capabilities. Extra virgin olive oil is doubtless considered one

of the most nutritious foods you can consume. If you consider you’re deficient

in magnesium, contemplate having some amaranth- you’ll

be glad you did once you discover out that it’s also a complete and wealthy source of protein. It is the

primary male sex hormone and plays an enormous position, along with its metabolite DHT, in making you a person. If

you think you studied you may have low testosterone, keep

away from supplements marketed as "testosterone boosters." As An Alternative, discuss with

a healthcare skilled for advice on secure,

evidence-based therapies. This part answers some widespread

questions about components which will affect testosterone

ranges and <a href="https://winacess.com/employer/9195/testosterone-booster-free-trial">the effects of using steroids are:</a> signs you might experience

with low testosterone. What’s extra, limited evidence suggests that supplementing with pomegranate juice could assist improve

levels of salivary testosterone in male athletes (19).

This improve leads to the accelerated conversion of testosterone into DHT (dihydrotestosterone), which is a stronger male hormone that can boost libido.

This mineral plays an important role in the manufacturing of thyroid hormones.

Bromelain acts in several ways to help larger testosterone ranges.

One is by maintaining high testosterone levels

even throughout damaging strenuous activities or endurance

training (as was demonstrated on this study).

Analysis has found it to also have some protecting results in opposition to cancer,

diabetes, and heart disease. The saying "You are what you eat"

also holds true for cows or any animal for that matter.

Cows food plan plays a major role in determining the standard of

their meat and its impact in your health when consumed. There are additionally

different oils that would increase testosterone, such as patchouli oil which is an plant oil.

Nevertheless, stay away from important oil from the mint family,

as they are all potent phytoestrogens.

As a society, we just don’t sleep sufficient, however the results of a 2014 study (45) proved notably

troubling for men who sleep five hours or much less a night.

Minimizing your stress levels can go a good distance towards maximizing your T ranges.

Breathing workout routines, meditation, and yoga can all help dial down stress.

Pomegranates contain more than 60 hydrolyzable tannins,

a lot of which account for the fruit’s antioxidant power.

As such, pomegranates may help cut back stress as

properly as the danger of cardiovascular disease, combat viruses,

and bacteria (26), and suppress inflammatory arthritis (27).

As far as fruit-bearing shrubs go, the pomegranate can do wonders.

Testosterone improves muscle mass, and this implies weight management and elevated

power. These benefits of testosterone get enhanced whenever you also embrace strength coaching in your routine.

Whey protein incorporates D-aspartic acid, an amino acid known to extend testosterone levels.

We’d argue though, that it’s primarily due to the bulb’s potassium content material (which is usually at approximately 150mg

per 100g). The mineral regulates testosterone concentrations and facilitates

other androgenic processes. L-dopa has been proven in scientific studies

to act as a direct precursor for dopamine which in flip also increase growth hormone.

More clinical trials are wanted to determine how onion can increase testosterone levels in humans.

Throw low-quality fats that don't assist testosterone manufacturing, and means an excessive amount of salt

and also you scarcely get any advantages from consuming these meats.

MUFA and SFA types of fat are essential for testosterone production and make extra

virgin olive oil a great inclusion to a food regimen geared at rising this hormone.

Subsequently, eating extra magnesium-rich meals, corresponding to spinach, kale, and collard

greens, could assist promote healthy testosterone ranges. Regardless, including sources of wholesome fats, similar to fatty fish, to

your diet will probably benefit your total health, together with hormonal well being.

Healthy testosterone ranges are important for both women and men. For folks dealing with low testosterone, these natural

remedies and foods that increase testosterone could possibly help normalize your ranges.

Studies on onion has up to now solely involved rodents, but the androgenic effects seen are fairly promising.

One explicit study showed a 300% average improve in testosterone ranges – and that’s from consuming onion juice.

Cabbage, Brussels sprouts, broccoli and cauliflower can all help naturally improve your testosterone levels by lowering estrogen levels.

We consider using oils from coconut and olives to be among the many

finest pure ways to extend testosterone. For frying food, coconut oil and butter is superior to

all different oils due to their high smoke level and resistance

to high temperatures. We wish to fry with coconut oil and use butter/olive oil with meals because of their good style.

These synthetic hormones can upset your natural hormone stability.

At the core of this issue is chopping out processed sugars from your

food regimen, which have been linked to insomnia,

obesity, diabetes and numerous hormone disorders. For

most males with low testosterone, when you wrestle with persistent stress, frustration, lack

of forgiveness, anger points, and so on., those issues all drop your testosterone ranges

over time. Analysis reveals that when your liver does

not perform optimally, it affects your testosterone output.

דודאני לא מכיר כל כך את סטרפ

דוד

אני לא מכיר כל כך את סטרפ אבל מנסיון שלי בתוכנות אחרות אז הבעיה תמיד זה ביחידות ובהגדרות

למשל כדאי שתבדוק את יחידות והגדרת המסה ואל תשכח לחלק את המשקל בתאוצת הכובד

תבדוק את הגדרת הכיוון של המסה כי אם אתה מחפש מוודים אופקיים אז גם המסה צריכה להיות מוגדרת בכיוון אופקי

בנוסף דע לך שהלימוד הכי טוב זה מהטעויות

בהצלחה

בעיקרון עשית הכל בסדר . תבדוק

בעיקרון עשית הכל בסדר . תבדוק אם הגדרות של התקן הם זהות . יכול להיות שמסה לא אותו דבר .

אם אתה גר בבאר שבע אני יכול לעזור לך .

דוד חשבתי על עוד משהואתה כותב

דוד חשבתי על עוד משהו

אתה כותב שאתה מכריח את הנקודות של צמתות חיבור הזיזים עם מישורי התקרות לנוע במישור

X1 X2 בלי לשנות את הגובה X3

אבל לא ציינת שאתה מאלץ את הנקודות האלה להשאר במרחק קבוע בין כל אחת לחברותיה

אהלן אריה וnemerתודה רבה על

אהלן אריה וnemer
תודה רבה על התגובות.
אריה לגבי תגובתך האחרונה , אני חושב שהפונקציה של rigid links בסטרפ אמורה לוודא שהנקודות אמורות להשאר במרחק קבוע זאת מזאת אבל אני בהחלט אבדוק את זה, תודה!
nemer תודה רבה על העזרה ואם זה על הפרק אני נמצא בב"ש בתחילת שבוע ,

תודה רבה ואני אעדכן אם יש התפתחויות

Understanding how certain foods can affect testosterone production is essential for anybody

trying to optimize their well being and well-being.

In this text, we’ll explore the connection between food plan and testosterone levels, and spotlight which meals would possibly enhance or hinder

this very important hormone. Consuming soy merchandise incessantly could result in lower testosterone levels, in accordance with some

studies, together with edamame, tofu, soy milk, and miso.

According to a study revealed in 35 men, consuming soy protein isolate for 54 days resulted in a lower

in testosterone levels (1–3). Edamame, a standard Japanese dish manufactured from

soybeans, is a well-liked health food. Eamme has been proven to

have numerous positive well being effects, however this is not at all times

true for men.

Total life-style components, together with diet, exercise, sleep, and stress management, all play a job in maintaining healthy testosterone ranges.

Subsequently, incorporating natural edamame right into a well-rounded, healthy lifestyle is key

to acquiring the most effective results. Melame, a type of soybean,

accommodates biologically similar chemical compounds to estrogen, a female

hormone. Soy is a meals that reduces the formation of estrogens in fats tissues, as nicely as its antioxidant and anti-inflammatory properties, which can help prevent

cancer progress. Tofu is a well-liked food among those following a vegetarian or vegan food plan,

as it's a nice supply of protein and other vitamins. Nonetheless, there was some controversy surrounding tofu's influence on testosterone levels in men.

You don't must eat tofu every day in order to stay healthy, but it might be a

useful device in your every day food regimen. Soy is thought

to lower estrogen ranges within the body, leading

to fewer temper swings and different symptoms of pre-malignant dysfunction in ladies.

Soy meals, like genistein, may contain isoflavones, which can cut back testosterone production. Soy

merchandise, corresponding to edamame, might have a unfavorable effect on testosterone

ranges if consumed in extreme quantities. You should schedule common health screenings,

eat a variety of foods, and focus on your health issues together with your physician. Don’t eat an unfamiliar meals or take a complement just since you were informed it was secure.

When ladies with PCOS consumed nuts greater in PUFAs, their plasma lipids and serum androgens

decreased. Five massive surveys of meals allergy prevalence in the US or

Canada based mostly on parent- or self-reported information, which doubtless overestimates prevalence,

have been published over the previous decade (498, 499, 513–515).

These surveys spotlight the variation in prevalence that exists among the many main allergens.

Among adults, soy allergy prevalence was reported to be 0.1, zero.16, 0.35 and 0.6%, which, in every case, made it the lowest prevalence of any of the most important allergens.

Amongst children and adolescents, these values have been 0.25, 0.32 and 0.5%, which as within the case of adults, made soy

the bottom prevalence. In Japan, seven food allergens,

of which soy just isn't one, require mandatory labeling whereas in Europe, 14 meals, certainly one of which is soy, require labeling

(511). Estimates are that greater than 9 million Americans have gout and greater than 32 million have hyperuricemia (436).

The concern comes largely from animal research or excessive instances

of people consuming huge amounts of soy. However when researchers

checked out males consuming regular quantities of soy, the story <a href="https://pediascape.science/wiki/Anavar_Cycle_Key_Information_and_Frequen... is the strongest steroid</a> very

completely different. Studies have instructed that isoflavones, which are compounds present in soy,

similar to edamame, might help to minimize back the C-reactive protein levels (and

thereby reduce inflammation). The best meals to lower excessive estrogen levels are fibre,

cruciferous greens, broccoli sprouts, green tea and probiotic-rich foods like sauerkraut.

Might scale back menopause symptoms Since soy

acts as a natural estrogen, it could assist scale back these symptoms.

In a evaluate of 35 studies, soy isoflavone supplements

raised estradiol (estrogen) ranges in postmenopausal ladies by

14% ( 14 ).

All these sources must be included as part of an total healthy diet

plan. Research have proven that consuming vegetable protein as a substitute

of animal proteins might cut back the risk of heart diseases[7].

A meta-analysis (one of most dependable scientific

strategies of research) [6] also confirmed that isoflavones or soy products didn't alter the bioavailable

T levels in males. This paper found that the scientific research

identified didn't provide any evidence that publicity to isoflavones affects the circulating levels of estrogen in men.

This meals is assumed to lower testosterone because of its phytoestrogen contents.

It is necessary to notice that whereas these elements might contribute to a decrease in testosterone ranges, individual responses may differ.

Isoflavones, can in concept, influence estrogen ranges by advantage

of results on enzymes concerned in steroid metabolism (315–318).

They could also influence biologically active levels of hormones

by affecting intercourse hormone binding globulin (SHBG) concentrations (319).

If you are worried about meals that mess with your hormones, together with testosterone ranges in girls, entire soy foods are better than processed ones.

Fermented soy merchandise might be even higher as a end result of they’re simpler to digest [1].

Please take a moment to learn the rules and familiarize yourself with Reddiquette earlier than posting.

In this research males within the experimental group have been requested to drink four hundred ml of soymilk every day over an 8-week interval whereas the control group

maintained their traditional food plan. Regardless Of widespread beliefs that certain nuts decrease testosterone, there may be very

little scientific evidence to help this.
