A mechanic uses a hydraulic car jack to lift the front end of a car to change the oil. The jack used exerts 8,915 N of force from the larger piston. To pump the jack, 444 N of force is exerted on the small piston, which has an area of 3.14 cm2. What is the area of the large piston?

Answer:

63.05 cm²

Explanation:

We use Pascals law to find the answer.

The law says that in an incomprehensible , non-viscous fluid the pressure applied will transmit through out the fluid without a change.

So, Pressure on larger piston = pressure on smaller piston.

      [tex]\frac{444}{3.14}  = \frac{8915}{A}[/tex]

                                     A ≅ 63.05 cm²
