An engine is mounted on four parallel springs. The engine operates at 3000 RPM. The weight of the engine causes the springs to deflect 10mm. Find the percent reduction of the force transmitted to the foundation provided by the springs. There are no dampers. Your answer should be expressed as a percentage (0 to 100).

True or false graphs must include scales that increase by the same amount
