Question

A cement block of length 18cm width 8cm and height 9cm exert a force of 30N on the floor . calculate A. the maximum and the least pressure it can exert.

Answer 1

Answer:

Least pressure = 1.66 Pascal

Maximum pressure = 3.75 Pascal

Explanation:

Least pressure will be seen when the surface area is maximum

So the least pressure will be on the surface of 18 cm .

So pressure = F/A

= 30/18 Pascal

= 1.66 Pascal

Now,

Maximum pressure will be seen on the least surface

So the maximum pressure would be in surface of 8 cm

So Pressure = F/A

= 30/8 Pascal

= 3.75 Pascal
