Chapter 13, Problem 1RQ

The force applied to a unit area is called

1. a. strain.
2. b. total force.
3. c. pressure.
4. d. none of the above.

To determine

Choose the option that represents the force applied to a unit area.

Answer to Problem 1RQ

The correct option is “$\underset{\_}{\text{c}\text{.}\text{pressure}}$”.

Explanation of Solution

Description:

Pressure:

The force applied per unit area is termed as the pressure. The pressure is measure in terms of Pascal, $\text{N}/{\text{m}}^2$, and $\text{kg}/\text{m}\cdot {\text{s}}^2$.

Strain: Strain is the deformation of an object due to an applied force. It is the ratio of change in length to the per unit length of an object.

From the analysis, it is clear that, the option c is an adequate option to represent the force per unit area.

Conclusion:

Hence, the correct option is “$\underset{\_}{\text{c}\text{.}\text{pressure}}$”.
