Question

a Rod is acted upon by two forces of magnitude of magnitude a 5N each. state the net effect of these forces if they act at two ends of the rod ,seperately by a distance of 3.5 m

Answer 1

Answer:

Here we apply two forces of same magnitude but opposite in direction.Hence we have F and - F which makes resultant force as zero.

Moment of force for F is r×F. For force F it has distance r therefore it has moment rF and same with force -F.Hence moment of force is rF.

The forces tend to rotate the body about the mid-point between the two forces.
