Question

Calculate the pressure exerted by a brick which applies a force of 1.2N when it is placed upright on the soil

Answer 1

Answer:

The answer is 1500N/m² .

Explanation:

We know that the force applied per unit area is called pressure.

Formula to calculate pressure is:

Pressure = Force / Area

In this case, only the force applied is given on an area of brick which is upright on the soil. The dimensions of the brick are not mentioned here which are 2cm x 4cm and 10 cm. Let the contact surface area be (0.02x0.04)m ².  

Now calculate pressure:

The force applied is 1.2 N

Pressure= Force /Area

Pressure = 1.2N/ (0.02x0.04)m²

= 1.2/0.0008 = 1500N/m²

Thus the pressure applied will be equal to 1500N/m².
