Question

Find the minimum and maximum horizontal force to be

applied on a block of mass M such that the block doesn’t

slide on the rough inclined surface which makes an angle

Ɵ with the horizontal. (Coefficient of friction between

block and floor is µ)​

Answer 1

Answer:

As it is asked for the minimum force required to push the body up the incline plane. it must be equal to the net maximum force acting along the plane of incline.

As it is asked for the minimum force required to push the body up the incline plane. it must be equal to the net maximum force acting along the plane of incline.So from the free body diagram, net force along the incline surface is μmgcosθ−mgsinθ

As it is asked for the minimum force required to push the body up the incline plane. it must be equal to the net maximum force acting along the plane of incline.So from the free body diagram, net force along the incline surface is μmgcosθ−mgsinθSo $$F >= μmgcosθ−mgsinθ$$
