Question

The modulus of elasticity of a material can be described as ________

(a) the product of stress and strain

(b) the ratio of stress to strain

(c) the product of yield point and strain

(d) the ratio of change in length to original length

I have been asked this question in my homework.

Asked question is from Physical Terms and Test Terms in portion Physical Test & Heat Treatment Terms of Aerospace Materials & Processes

Answer 1

Right choice is (b) the ratio of stress to strain

Easiest explanation: The ratio of stress to strain is called the modulus of elasticity (within the elastic limit). The ratio of change in length to original length is called strain.
