Distribution of Pressure

a person of m...

Question

a person of mass 50 kg has his 1 foot area as 180 cm². assuming that g =10m/s². calculate pressure exerted on ground

Open in App

Solution

Since, Pressure = Force/ area
Given, mass = 50 kg
Here, force is equal to the weight of the body, i.e F = W = mg = 50 X 10 = 500 N
Area = 180 cm² = 18 X 10^-3 m²
So, P = 500/18 X 10^-3 = 27.77 X 10³ N/m².
