Homework Statement
Find the angle Theta so that the system is in equilibrium
Mass of each block: 2 Kg
Mass of ring: 4π Kg
Homework Equations
Static equilibrium:
Rotational equilibrium
The Attempt at a Solution
Static equilibrium:
2g + 2g + 4πg = Normal
N = 4g + 4πg
Taking the torque with respect to the center of mass:
(N*(cosθ + sinθ)*2R*√2)/√2 * 3π + g*R(cosθ-sinθ) = [ 2*g*(cosθ+sinθ)*( (R/√2) + (2R√2)/3π) ] / √2 + 2*g*cosθ *(R + 2R/3π) + 2g*sinθ*(2R/3π)
This doesn't lead me anywhere.
Thanks for your help
