A force of $100N$ is applied on a car through the hydraulic jack. The area of the base on which the car is resting is ​
$100m^2$ and the area of the effort side is $50m^2$. Find the force exerted on the car through the hydraulic press.​

Q. The mechanical advantage of a hydraulic press is 5. A car of mass 1500 kg is lifted by it when placed on a piston of a hydraulic press of area of cross section $5m^2$. Find the area of cross-section of piston where the effort is applied.

Q. In a typical hydraulic press, a force of 20 N is exerted on small piston of area 0.050 m2. What is force exerted by large piston on load if it has an area of 0.50 m2?

Q. A force of 2 x ${10}^4$ is applied to the larger piston of a hydraulic machine of $900c{m}^2$ in area. Neglecting friction, calculate the force exerted on the smaller piston of area $10c{m}^2$ to accomplish this task.

Q. The small piston of a hydraulic lift has an area of $0.20m^2$. A car weighing $1.20\times {10}^{4}N$ sits on a rack mounted on the large piston. The large piston has an area of $0.90m^2$. How large a force must be applied to the small piston to support the car?
