Elastic limit is the maximum stress to which body can be subjected without permanent deformation
Thus, option (2) is correct.
SI unit of Stress is N/m²
Thus, option (1) is correct.
Explanation:
Elastic limit is the limit upto which a body when stresses will come back to its original state.
Therefore,
Elastic limit is the maximum stress to which body can be subjected without permanent deformation
Therefore, option (2) is correct.
Stress = Force/Area
Therefore,
Unit of stress in SI units= Unit of Force in SI units/Unit of area in SI units
or, Unit of Stress = Newton/square metre = N/m²
Therefore, option (1) is correct.
