Question

What is the standard unit of stress in Metric Units?

Answer 1

The stress element is that of pressure intensity, and its co-ordinates are most generally expressed in the same metrics as pressure: pascals which is equal to newtons per square meter (N/m^2). And in the International System or in the Imperial System it expressed in pounds per square inch (psi)

Explanation:

Stress is a physical quantity representing the internal forces exerted on each other by the neighboring particles of a solid substance.

Stress is often expressed by a Greek lowercase letter sigma which is written as
`\sigma`

The stress element is that of pressure intensity, and its co-ordinates are most generally expressed in the same metrics as pressure: pascals which is equal to newtons per square meter (N/m^2). And in the International System or in the Imperial System it expressed in pounds per square inch (psi).

`1\ pascal = 1 N/m^2`

Answer 2

Pascal(Pa)

Explanation:

We have to find the standard unit of stress in metric units

We know that

Stress: it is defined as the force per unit area.It is also called pressure .

Mathematical representation

`Stress=(force)/(area)`

S.I units of force=Newton=N

S.I Unit of area=
`m^2`

S.I Unit of stress=
`N m^(-2)=Pascal`

Hence, S.I unit of stress in metric units is pascal(Pa).
