Question

8.
Define Young's, modulus of elasticity. Give its units and dimensions​

Answer 1

Explanation:

This is a specific form of Hooke's law of elasticity. The units of Young's modulus in the English system are pounds per square inch (psi), and in the metric system newtons per square metre (N/m2). The value of Young's modulus for aluminum is about 1.0 × 107 psi, or 7.0 × 1010 N/m2.

Answer 2

Explanation:

Young's modules is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression . Sometimes is referd to as a modules of elasticity. Young's modules is equal to the longitudinal stress divided by the strain.
