Question

An elephant has four legs one leg exerts force of 1000 Newton area of one leg is 1 cm Square find out the pressure exerted by all four legs?

Answer 1

Answer:

Given: 1) Force exerted by 1 leg = 1000 N

by 4 legs = 4000N

2) Are covered by 1 leg = 1 sq.cm.

by 4 legs = 4 sq.cm.=4×10^-2 sq.m.

To find : Pressure exerted by 4 legs = ?

Solution:

$pressure = force \div area$

Pressure = 4000/4×10^-2

= 1000 × 10^2

= 100× 10^3 Pa

= 100 kPa
