A hydraulic press has a safety feature which consists of a hydraulic cylinder with a piston at one end and a safety valve at the other. The cylinder has a radius of 0.0220 m and the safety valve is simply a 0.00600-m radius circular opening at one end, sealed with a disk. The disk is held in place by a spring with a spring constant of 825 N/m that has been compressed 0.0095 m from its natural length. Determine the magnitude of the minimum force that must be exerted on the piston in order to open the safety valve.
