When the 0.8 kg uniform rod AB is in the vertical position, the two springs of stiffness k = 1450 N/m are unstretched. The weight of the horizontal bar attached to the rod at A is negligible. If the support C undergoes the harmonic angular displacement β(t) = β0 sin ωt, where β0 = 2? and ω = 7.5 rad/s, find the steady-state angular amplitude of bar AB.
