ICSE Class 10 Physics 2023 Solved Paper

The diagram shows wheel O pivoted at point A. Three equal forces F1,F2 and F3 act at point B on the wheel.

Question : 22

Total: 76

Give a reason for your answer in (a).

Solution:

Because the force F1 is tangential to the wheel. So, the perpendicular distance of pivoted point A is maximum from the line of action of the force F1. Thus, its moment about A will be maximum.
