Suppose a car sitting on a hydraulic lift exerts a downward force of 1,750 N on a piston with an area of 0.6m^3. How much pressure does the car exert on the piston?

Pressure is defined as force per unit area, which in this case works out to be 2.917 kPa


One pascal of pressure is exerted by a force of one newton applied over an area of one square metre.

So, for a 1750 N force applied to 0.6 #m^3#, we find

#P=F/A# = #(1750N)/(0.6 m^3)# = 2917 Pa or 2.917 kPa
