You are designing a hydraulic lift for an automobile garage. It will consist of two oil-filled cylindrical pipes of different diameters. A worker pushes down on a piston at one end (d = 25cm), raising the car on a platform at the other end (d=?). To handle a full range of jobs, you must be able to lift cars up to 3000 kg, plus the 700 kg platform on which they are parked. To avoid injury to your workers, the maximum amount of force a worker should need to exert is 100 N. What should be the diameter of the pipe under the platform? If the worker pushes down with a stroke 50 cm long, by how much will he raise the car at the other end?

Air is contained in a frictionless piston-cylinder assembly as shown below. The initial equilibrium position is subjected to atmospheric pressure of 100 KPa. The mass of piston and weight together is 200 kg. The piston has a diameter of 0.452 m. The initial temperature of the gas in the container is 800 K. Take C, = (7/2) R and Cy = (5/2) R, calculate the following: (a) force exerted by the piston, weight, and the atmosphere in N (b) total pressure of air in the container in kPa (note: at initial equilibrium position, the Peas = Pop) (c) total moles of air in the container (assume air behaves ideally)

A frictionless piston/cylinder assembly A shown in the figure is connected by a thin pipeline with a valve to a rigid tank B. The volume of tank B is 1.0 m³, and the cross-sectional area of the piston is Aa = 1.2 m?. Initially (state 1) the valve is closed, 3 kg of argon is enclosed in the piston/cylinder assembly, mĄ1 = 3 kg, and there is no argon in the tank, mg,1=0. The initial temperature of the argon is TĄ1 = 50°C and the initial volume of the gas enclosed by the piston cylinder is VA1 = 1.5 m?. The valve is slowly opened allowing argon to flow into the tank. The valve is then closed when the piston just touches the stops but does not exert a force on the stops (state 2). At state 2, the temperature and pressure throughout the tank and piston/cylinder system are equal (Pa2 = P8,2 and Ta2= T82). The height from the bottom of the cylinder A to the top of the stops is htops = 0.5 m. The volume of the stops can be assumed negligible. Treat argon as an ideal gas. a) Determine the…
