Question

a regular concrete block of mass 100kg has dimensions 200cm x 100cm x 50cm. Calculate the greatest possible pressure the block will exert on the ground.​

Answer 1

Answer:

Greatest pressure on the ground is 1962 Pa

Explanation:

As we know that pressure is ratio of force and area

so we can write its equation as

$P = \frac{F}{A}}$

now here we need to find the greatest pressure on the ground

here force is due weight of the object and area must be minimum in contact with the ground

F = mg

$F = 100(9.81)$

$F = 981 N$

Now minimum area of contact with the ground is

$A = 0.50 \times 1 = 0.5 m^2$

now maximum pressure is given as

$P = \frac{981}{0.5}$

$P = 1962 Pa$
