what is the pressure exerted on the floor by each leg of the chair?
A large man sits on a four-legged chair with his feet off the floor. The combined mass of the man and chair is 95.0 kg. If the chair legs are circular and have a radius of 0.600 cm at the bottom, what pressure does each leg exert on the floor?
Total weight of man and chair = 95 * 9.8 = 931 newtons
The force acting on each leg = F = 931/4 = 232.75 newtons
A = Area of chair’s leg = π(0.600 cm/100 cm/m)^2
A = 0.0001 m^2
Since,
Pressure = P = Force/Area, then
P = 931/0.0001
P = 9,310,000 N/m^2
Hope this helps.
