    U = 0.75 MPa

    Therefore, the modulus of resilience for the tensile test specimen is 0.75MPa

    Explanation:

    The Modulus of resilience can be derived from the area under the elastic portion of the stress-strain diagram. It can be written mathematically as;

    U = 1/2 * yield strength * yield strain.

    Where U is the modulus of resilience.

    Given;

    Yield strength = 500MPa

    Yield strain = 0.003

    Substituting the given values we have;

    U = 1/2 * 500MPa * 0.003

    U = 0.75 MPa

    Therefore, the modulus of resilience for the tensile test specimen is 0.75MPa

    The modulus of resilience is 166.67 MPa

    Explanation:

    Modulus of resilience is given by yield strength : strain

    Yield strength = 500 MPa

    Strain = 0.003

    Modulus of resilience = 500 MPa : 0.003 = 166.67 MPa
