Container Beam Spring In the figure, a spring of spring constant k-31.5 kN/m is between a rigid beam and the output piston of a hydraulic lever. An empty container with negligible mass sits on the input piston. The input piston has area A-1.41 m² and the output piston has area A, 4.47 m². Initially the spring is at its rest length. How many kilograms of sand must be (slowly) poured into the container to compress the spring by 4.02 cm? mand" kg
