A cube with a volume of 1 cubic decimeter and a mass of 2 kg is placed in the center of a horizontal desktop with an area of 0.5 square meters, (1) How much pressure is on the desktop? (2) What is the stress area? (3) What is the pressure of the object on the table? (g = 9.8N / kg)

A cube with a volume of 1 cubic decimeter and a mass of 2 kg is placed in the center of a horizontal desktop with an area of 0.5 square meters, (1) How much pressure is on the desktop? (2) What is the stress area? (3) What is the pressure of the object on the table? (g = 9.8N / kg)


1) Pressure on desktop: 2 * 9.8 = 19.6n
2) Stressed area: 0.5 M2
3) The pressure of the object on the table: 19.6 △ 0.5 = 39.2pa
