The SI unit of stress is same as the SI unit of
Strain
Pressure
Modulus of elasticity
Both (B) and (C)
Modulus of elasticity
The explanation for the correct option:
In the case of option B,
Stress can be calculated by,
Where,
is Stress.
is Force.
is Area.
SI unit of force () is Newton and is meter square .
SI unit of Stress is .
Pressure can be calculated by,
Where,
is Pressure.
is Force.
is Area.
In the case of option C (modulus of elasticity),
The explanation for the incorrect options:
In the case of option A (strain),
Therefore, the correct option is B&C.
