Question

A 7.5 kg block is placed on a table . If it's bottom surface area is 0.6m2 how much pressure does the block exert on the table top?

Answer 1

Pressure is defined as the force per unit area. This measurement is more convenient to use for describing a force exerted. The standard unit for pressure is Pascal. For this problem, force is the gravitational pull from the block. Calculations are as follows:

P = F/A where F = mg

F = 7.5 ( 9.81) = 73.6 N

P = 73.6 N / 0.6 m^2 = 122.6 Pa
