Question

a 2000lb car is on a hydraulic lift, what it the pressure is the side of the lift has a 20cm diameter?

Answer 1

Pressure = Force / Area

Answer 2

convert units to SI to make it easier

Answer 3

2000lb (kg ) = 909kg
2.2lb

Answer 4

Area...
d = 20 cm = .2m
A = pi r^2 = pi .1m^2 = .0314m^2

Answer 5

Force = mass x gravity = 909kg x 10m/s^2 = 9090N

Answer 6

P = F/A
P = 9090N/.0314m^2 = 289,490Pa

Answer 7

There's your answer :)
