The spool of wire having a mass M rests on the ground at A and against the wall at B. Determine the force P required to begin pulling the wire horizontally off the spool. The coefficient of static friction between the spool and its points of contact is μs.

Units Used:

kN = 103 N

Given:

M = 150 kg

μ s = 0.25

a = 0.45 m

b = 0.25 m
