N m Free Body Diagrams The figure below shows a mechanical assembly consisting of a horizontal piston cylinder that contains a pressurized gas with a pressure larger that the atmospheric pressure Patm 1 105 piston is locked with a pin such that it does not move On the outside of the assembly there is a spring of Initially the known elastic constant k 1 104 The piston has two circular surfaces of equal area A 0 025 m Initially as shown in the figure the spring is at its non deformed position neither stretched nor compressed Next the locking pin is removed and the piston moves to the right until it finds a new equilibrium position Please answer the following questions N m Gas O Feas O Fatm Piston A 0 025 m force due to gas force due to atmosphere Patm 1x10 N m Spring k 1x10 N m Locking pin a Indicate all the important forces you would include on a free body diagram FBD for the horizontal forces acting on the piston before the locking pin is removed Note that the friction between the wall of the cylinder and the piston is neglected O Rx OFs reaction force due to pin force due to spring
