1.A vibration generator is placed on the deck to test the bridge under simulated earthquake loads. The generator produces a load of p(t) = (100 kip) sint, where the forcing frequency, = 6.28 Hz. The stiffness of the bridge is k = 200 kip/in. Calculate the maximum steady-state displacement and acceleration of the deck. Assume 5% damping ratio, and n = 5.49
