Answer to Problem 1CQ

The elastic modulus of material decreases with increase in temperature

Explanation of Solution

Elastic modulus can be defined as the ratio of applied stress to the obtained strain in the body up to proportional limit. Elastic modulus can also be defined as the slope of curve for applied stress versus strain in specimen up to the elastic limit of material.

Elastic modulus is a mechanical property of a material and it depends on the temperature of material. The modulus of Elasticity of material is directly proportional to its change in temperature. As the temperature of material increase the elastic modulus of material decreases proportionally.

When the temperature increases, the distance between the atoms in the material increases and they move farther from each other. Increasing temperature reduces the strength of material and its elastic modulus.

Conclusion:

Thus, the elastic modulus of material decreases with increase in temperature

A specimen of steel has a rectangular cross section 20 mm wide and 40 mm thick, an elastic modulus of 207 GPa, and a Poisson's ratio of 0.30. If this specimen is pulled in tension with a force of 60,000 N, what is the change in width if deformation is totally elastic? O Increase in width of 3.62 x 10-6 m O Decrease in width of 7.24 x 10-6 m Increase in width of 7.24 x 106 m O Decrease in width of 2.18 x 10-6 m
