Question

A block weighing 1200 Newton rests on an area of 4m square.calculate the pressure exerted by the block on the surface.

Answer 1

Given:

A block weighing 1200 Newton rests on an area of 4m².

To Find:

What is the pressure exerted by the block on the surface.?

Solution:

Wight = Force = Lateral force = F = 1200 N

Area of block on contact surface:

Area = A = 4 m²

We know the formula of pressure, which are given below:

$\mathbf{Pressure=\dfrac{Force}{Area}}$

$\mathbf{Pressure=\dfrac{1200}{4}}$

$\mathbf{Pressure=300 \ \dfrac{N}{m^{2}}=300 \ \ Pa}$

Means pressure exerted by weight on contact surface is 300 Pascal.
