A medium sized car typically weighs 1000kg.

Gravity force = 9.8 N/Kg
A hydraulic system to jack the care up above an inspection pit has for slave cylinders whose pistons have a cross section area of 0.01m2. The cross-section area of the master cylinder piston is 0.00125m2.

What is the weight of the car?

Answer:

39200 N.

Step-by-step explanation:

To calculate the weight of the car, we use the concept of hydraulic pressure in the hydraulic system. The force exerted by the master cylinder is equal to the weight of the car, which is transmitted to each of the four slave cylinders evenly. Using the formula for force, we find the force exerted by the master cylinder to be 9800 N. Since each slave cylinder exerts the same force, the total force exerted by all four slave cylinders combined is 39200 N. This total force is equal to the weight of the car, which is 39200 N.
