Question: Determine the smallest force the man must exert on the rope in order to move the crate of mass M. Also, what is the angle

Determine the smallest force the man must exert on the rope in order to move the crate of mass M. Also, what is the angle θ at this moment? The coefficient of static friction between the crate and the floor is μs.


Given:

M = 80 kg

μ s = 0.3

α = 30 deg

β = 45 deg

g = 9.81m/s2
