Question

A block of weight 100N
and dimensions 50 cm x 30 cm x 10 cm rest on a table in 3 different positions with its base as a)50 cm x 30 cm
b)30 cm x 10 cm
c)50 cm x 10 cm
calculate pressure exerted in each case.

Answer 1

Explanation:

a) P = F/A

= 100/(50/100)(30/100)

= 666.67 N/m^2

b) P = F/A

= 100/(30/100)(10/100)

= 3333.3344 N/m^2

c) P = F/A

= 100/(50/100)(10/100)

= 2000 N/m^2
