An electric motor of mass 68 kg is mounted on an isolator block of mass 1200 kg and the natural frequency of the total assembly is 160 cpm with a damping factor of = 0.10 (see Fig.). If there is an unbalance in the motor that results in a harmonie force of F = 100 sin( 31.41), determine the amplitude of vibration of the block and the force transmitted the floor.
