The table weighing 50kg has 4 legs. The area of each leg is 100cm square. How much pressure is exerted by the weight of the table on the surface.
m = 50 kg
S1 = 100cm ^ 2 = 0.01m ^ 2
g = 10 m / s ^ 2
P-?
Pressure P is the ratio of the force F to the area S on which this force acts. P = F / S. The gravity force F = m * g acts on the table, the table has 4 legs, the area of each is S1, so the total area will be S = 4 * S1. The formula for finding the pressure will be P = m * g / 4 * S1. P = 50 kg * 10 m / s ^ 2/4 * 0.01 m ^ 2 = 12500 Pa.
Answer: the table exerts a pressure P = 12500 Pa on the surface.
