Answer:
Pascal(Pa)
Step-by-step 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
[tex]Stress=\frac{force}{area}[/tex]
S.I units of force=Newton=N
S.I Unit of area=[tex]m^2[/tex]
S.I Unit of stress=[tex]N m^{-2}=Pascal[/tex]
Hence, S.I unit of stress in metric units is pascal(Pa).
Answer:
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)
Step-by-step 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 [tex]\sigma[/tex]
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).
[tex]1\ pascal = 1 N/m^2[/tex]
