Question

an elephant of mass 1500kg stands on its four legs each of area 0.012m^2, calculate the pressure exerted by each leg of the elephant on the ground.(g=10m/s)?

Answer 1

Given:

$m=1500\:\rm kg$

$A=4*0.012\:\rm m^2=0.048\: m^2$

The pressure

$$P=mg/A\\ =\frac{1500\:\rm kg*10\: N/kg}{0.048\:\rm m^2}=312500\:\rm Pa$$
