Question: A chain having a length L and weight W rests on a street for which the coefficient of static friction is s. If a crane

A chain having a length L and weight W rests on a street for which the coefficient of static friction is μs. If a crane is used to hoist the chain, determine the force P it applies to the chain if the length of chain remaining on the ground begins to slip when the horizontal component is Px. What length of chain remains on the ground?

Given:

L = 20 ft

W = 8lb/ft

μs = 0.2

Px = 10 lb

A chain having a length L and weight W rests on a street for
