Question

Determine pressure exerted by cuboid (of weight 10 N) in the following cases.​

Answer 1

Answer:

Theory

1.Thrust: The net force exerted by a body in a particular direction. (Thrust = weight of body)

2.This force is perpendicular to the surface. When you stand on loose sand or lie down on the sand, the thrust acting on the surface is same, but the effects are different. Pressure increases with decrease in the area of contact. S.I. unit of Thrust is newton (N).

3.Pressure: The thrust acting on unit area is called pressure.

4.S.I. unit of pressure = (N m-2) or pascal (Pa)

1 Pa = 1 N/l m2
