A 12,000-N car is raised using a hydraulic lift, which consists of a U-tube with arms of unequal areas, filled with incompressib

Answer:

926 N

Explanation:

Metric unit conversion:

R = 18 cm = 0.18 m

r = 5 cm = 0.05 m

The pressure exerted by the F = 12000N car on the wider arm would be ratio of the gravity over area

$P = F/A = \frac{F}\pi R^2} = \frac{12000}{2*\pi*0.18^2} = 117892 Pa$

The pressure must be the same on the smaller pressure for it to be able to start lifting the car. We can calculate the force f acting on it:

$f = Pa = P\pi r^2 = 117892 * \pi * 0.05^2 = 926 N$
