Chapter 14, Problem 31R

To determine

The term that describes the amount of the force exerted on the per unit of the area.

Answer to Problem 31R

The amount of the force exerted per unit area of the object describes the term pressure.

Explanation of Solution

Introduction:

The effect of the force on a certain area varies with the variation in the force and area. If the force acts on the small area, the effect of the force will be greater than the large area.

The exerted force on the unit area of the object is described by the term “Pressure.” The atmospheric air above the surface of the earth exerts the pressure, which is called the atmospheric pressure. The value of the atmospheric pressure is 101 kPa.

Conclusion:

Thus, the amount of the force exerted per unit area of the object describes the term pressure.
