Question

1. A 1500kg car is being lifted by a hydraulic jack attached to a flat plate. Underneath the plate is

a pipe with radius 24cm.

a) If there is no net force on the car, calculate the pressure in the pipe.

Answer 1

the pressure in the pipe in the case when there is no net force on the car is 81,726 N/m^2

Step-by-step explanation:

a. The computation of the pressure in the pipe in the case when there is no net force on the car is shown below

As we know that

Pressure = F ÷ area

Also

F = mg

Now

= (1500 × 9.8) ÷π (0.24)^2

= 81,726 N/m^2

Hence, the pressure in the pipe in the case when there is no net force on the car is 81,726 N/m^2
