Question

Calculate the pressure exerted by a brick, which applies a force of 30N, when
a) it is placed upright on the soil.
b) when it is placed on its widest base.

length = 29 cm Width = 10 cm height = 5 cm ​

Answer 1

Explanation:

when it is placed upright,

area in contact=height x width= 0.5m since SI unit is metres

P=F/A=30/0.5≈60 Pascal or any other equivalent unit

similarly,

area in contact in second=length x width=2.9m

P=30/2.9≈01 P
