Question:
The disk has mass M and is supported on the smooth cylindrical surface by a spring having stiffness k and unstretched length l0. The spring remains in the horizontal position since its end A is attached to the small roller guide which has negligible weight. Determine the angle θ to the nearest degree for equilibrium of the roller.
Given:
M = 20 kg
k = 400N/m
l0 = 1 m
r = 2 m
g = 9.81m/s2
a = 0.2 m
Guesses F = 10 N R = 10 N θ = 30 deg
