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
S.I units of force=Newton=N
S.I Unit of area=
S.I Unit of stress=
Hence, S.I unit of stress in metric units is pascal(Pa).
