Question:

A roofer, having a mass M, walks slowly in an upright position down along the surface of a dome that has a radius of curvature ρ. If the coefficient of static friction between his shoes and the dome is μs determine the angle θ at which he first begins to slip.

Given:

M = 70 kg

ρ = 20 m

μs = 0.7
