Question

question 9
how can we define modulus of elasticity?
all of the above
ratio of unit stress to strain along one axis
indication of a degree of stiffness of a material
e = direct stress / strain

Explanation:

The modulus of elasticity is defined as the ratio of unit - stress to strain along one axis (also written as E = direct stress/strain), and it is an indication of the degree of stiffness of a material. So all the given options are correct.

Answer:

A. all of the above
