PROBLEM 10.76 A block of mass mis hung from member ABas shown. Neglecting the mass of ABand knowing that the spring is unstretched when 20 ,θ=°determine the value of corresponding to equilibrium when 3 kg.m=State whether the equilibrium is stable, unstable, or neutral. SOLUTION Using the general results of Problem 10.76 and noting that now 03 kg, and 20m==°we have Equilibrium()200:sin0ABdVkrmgLdθθ=−−=()22
