when two forces act on a body in opposite direction along strike line one of the force should be the another to change the state of motion of your body |
|
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.I hope it will be helpful to you FRIEND |
