PROBLEM 10.72 Two uniform rods, AB and CD , are attached to gears of equal radii as shown. Knowing that 3.5 kg AB m = and 1.75 kg, CD m = determine the positions of equilibrium of the system and state in each case whether the equilibrium is stable, unstable, or neutral. SOLUTION Potential Energy ( ) ( ) 2 2 3.5 kg 9.81m/s sin 1.75 kg 9.81m/s cos 2 2 l l V θ θ = × + × ( ) ( ) 8.5838 N 2sin cos l θ θ = + ( ) ( ) 8.5838 N 2cos sin dV l d θ θ θ = ( ) ( ) 2 2 8.5838 N 2sin cos d V l d θ θ θ = Equilibrium: 0: 2cos sin 0 dV d θ θ θ = = or tan
