Asked by sonam
in a car, compressed air exerts a force F1 on a small piston having a radius of 5cm. this pressure is transmitted to a second piston of radius 15cm.if the mass of car to be lifted is 1350kg ,what is the force F1 necessary to accomplish this task?

the pressure on each piston is the same:
Pressure=force/area
force2/area2=force1/area1
force1=1350*9.8N * (5/15)^2
Pressure=force/area
force2/area2=force1/area1
force1=1350*9.8N * (5/15)^2
