Piston 1 in the figure has a diameter of 0.24 in and is attached to a lever arm a distance 2 in from the pivot point. Piston 2 has a diameter of 1.6 in. An external force F acts on the lever arm at a distance 20 in from piston 1 as shown below. 465 1b 2 in 20 in 2 F In the absence of friction, find the forceF necessary to support. the 465 lb weight. Assume the height difference between the piss- tons is negligible. Answer in units of 1b \feally on the bottom of a large beaker of water. A 4.09 kg block of wood of density 603 kg/1113 is connected to the top of the spring and the block-spring system is allowed to come to static equilibriun1.| \"that is the elongation AL of the spring"? The acceleration of gravity is 9.8 111/52 . Answer in units of cm A piston A has a diameter of 0.83 cm, as shown. A second piston B has a diameter of 2.8 cm. 565.8 N F B A In the absence of friction, determine the magnitude of the force F necessary to support the 565.8 N weight. Answer in units of N
