The compound pendulum of mass m and radius of gyration k_o about O is freely hinged to the trolley, which is given a constant horizontal acceleration a from rest with the pendulum initially at rest with θ = 0. Determine an expression for the angular acceleration ? and the n- and t-components of the force at O as functions of θ. Calculate the maximum value reached by θ if a = 0.5g.
