Physics question about density and pressure? - what is the pressure exerted on the floor by each leg
A great man is on a four-legged chair with his feet on the ground. The total mass of the man and the chair is 95.0 kilograms. If the chair legs and have a circle with a radius of 0.400 cm on the ground that the pressure exerted by the two legs on the ground?

What Is The Pressure Exerted On The Floor By Each Leg Physics Question About Density And Pressure?

Compressive force is divided by the area.
The force F = (95.0 kilograms) (9.8 m / s ²) = 637 N.
Zone A = (4) (πr ²) = (4) (π) (.004 m) ² = 000,201 m²
The total pressure is P = 3.17 million newtons per square meter.
Each step takes one fourth of the total of 792,000 N / m
