WebbThe rotation of the screw tends to raise the load (move it up the incline), the friction force opposes the motion and acts down the plane. Raising the load requires an axial force P as shown in the picture. N is the normal force and the force due to friction then acts to oppose the motion up the plane and is given by μ ⋅N μ ⋅ N. http://ignou.ac.in/upload/Unit-2-56.pdf
