חישוב מעקה

שלום,
חישוב מעקה:
נתונים: 2 פחים באורך 120 ס"מ בעובי 0.8 ס"מ רוחב משתנה 4 ס"מ חלק עליון 10 ס"מ תחתון
הכוח המופעל בקצה העליון 150 ק"ג.
כדי לבדוק עם המעקה עומד בחוזק עלי להשתמש בנוסחה למצוא את מודול החתך W, במקרה זה h הוא המשתנה.
באיזה רוחב עלי להשתמש? רוחב ממוצע?

אם אתה מעוניין לחשב את המומנט

אם אתה מעוניין לחשב את המומנט בנקודת הריתום שם הוא הכי גדול- תשתמש בחתך ששם.
אם אתה רוצה לבדוק את מרכז המהלך, תחשב לפי החתך באותו גובה.
