Question

The force of 5N acts at a distance of 0.5 m, a force of 2 N acts at a distance of 0.25 m. If on the other side 6 N weight is put at what distance should it be applied to keep the ruler straight?​

Answer 1

Answer:

Explanation:

moment = force x perpendicular distance from turning point. You consider the weight of the aluminium beam to act through its centre of mass 2.5 m from either end, but it is 0.5 m from the steel rod which is effectively the pivot point on which you base your moment calculations
