Question: If the collar P is given a constant acceleration a = 3g to the right, the pendulum will assume a steady-state deflection = 30.

If the collar P is given a constant acceleration a = 3g to the right, the pendulum will assume a steady-state deflection θ = 30°. Determine the stiffness k_T of the torsional spring which will allow this to happen. The torsional spring is undeformed when the pendulum is in the vertical position.
