roll of paper has a uniform weight of 2kN and is suspended from the wire hanger so that it rests against the wall. If the hanger has a negligible weight and the bearing at O can be considered frictionless, determine the force P needed to start turning the roll if = 30°. The coefficient of static friction between the wall ܬܐ and the paper is µ = 0.3.

A roll of paper has a uniform weight of 2kN and is suspended from the wire
hanger so that it rests against the wall. If the hanger has a negligible weight and
the bearing at O can be considered frictionless, determine the force P needed to
start turning the roll if 0 = 30°. The coefficient of static friction between the wall
and the paper is µ = 0.3.
