Find the force required to move a load of 30N up a rough inclined plane, applied parallel to the plane. The inclination of the plane is such that when the same body is kept on a perfectly smooth plane inclined at an angle, a force of 6N applied at an inclination of 30" to the plane keeps the same in equilibrium. Assume coefficient of friction between the rough plane and the load is equal to 0.3.

A rough inclined plane, rises 1cm for every 5 cm along the inclined length. Calculate the effort required to drag a body weighing 100N up the plane, when the effort is applied parallel to the plane (µ=0.25)

1000 lb trunch the black resting on the incline plan has a mass of 60g. determine maximum and minimum value of P for which the block is in equilibrium. (fs = 0.35)

What is the frictional HP acting on a collar loaded with 100 kg weight? The collar has an outside diameter of 100 mm and an internal diameter of 40mm. The collar rotates at 1000 rpm and the coefficient of friction between the collar and the pivot surface is 0.15.
