An industrial machine weighing 1000 lb is supported by springswith a static deflection of 0.20 inches. The machine has a rotaryunbalance of 20 lb / in. If this machine is mounted on a largeconcrete block weighing 2500 lb and the stiffness of the springs orsupports under the block is increased so that the static deflectionis still 0.20 in, what will be the dynamic amplitude?
