Fig. 3.1 shows a hydraulic lift in a car repair workshop.
The hydraulic fluid transmits the pressure, caused by piston A, equally to each of the four
pistons holding up the car supports. The pressure throughout the quid is the same.
A force of 1000 N on piston A is just enough to raise the car.
(a) Using values from Fig. 3.1, find
o the pressure caused by piston A on the fluid,
