The figure below shows a gas contained in a vertical piston-cylinder assembly. A vertical shaft whose cross-sectional area is 0.8 cm? is attached to the top of the piston. Determine the magnitude, F, of the force acting on the shaft, in N, required if the gas pressure is 3 bar. The masses of the piston and attached shaft are 24.5 kg and0.5 kg, respectively. The piston diameter is D = 5 cm. The local atmospheric pressure is 1 bar. The piston moves smoothly in the cylinder and g = 9.81 m/s?. Using multiple attempts will impact your score.20% score reduction after attempt 1 As shown in the figure below, air is contained in a vertical piston-cylinder assembly such that the piston is in static equilibrium. The atmosphere exerts a pressure of 14.7 Ibf/in. on top of the 8-in-diameter piston. The absolute pressure of the air inside the cylinder is 16 lbf/in. The local acceleration of gravity is g-32.2 ft/s. Determine (a) the mass of the piston, in Ib, and (b) the gage pressure of the air in the cylinder, in psig,
