Paper Details

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 ?s.
Units Used:
kN = 103 N
Given:
M = 150 kg
? s = 0.25
a = 0.45 m
b = 0.25 m
