A storage cabinet has a total weight of 480 N and is supported by four identical feet. Each foot has a flat area of 6.0 cm2 in contact with the floor.
State the equation relating pressure, force, and area.
Calculate the pressure exerted on the floor by each individual foot of the cabinet. Give a suitable unit for your answer.
To protect the floor from damage, flat protective cups with wider bases are placed under each foot of the cabinet. Explain, in terms of pressure, force, and area, why using these protective cups reduces the risk of floor damage.
