The piston of a hydraulic aut0mobile lift is .30m in diameter. What gauge pressure, in pascals, is required to lift a car with a mass of 800kg? Also express this pressure in atmospheres.

Hook them up to a flasher unit.
you buy them as flashing Christmas light. You don't have to do anything, just plug them in and they flash. Merry christmas
800kg / pi {(1/2)(0.30m)}^2 Now convert the kg/m^2 to pascals.

w8 of the car is wm*g, and this w8 yields pressure Pw/A, where area Api*(0.3/2)^2; thus P800*9.8 / (pi*(0.3/2)^2) 110913 Pa ≈ 1.1 atm;
