A steel cable supports an actor as he swings onto the stage. The weight of the actor stretches the steel cable. To describe the relationship between stress and strain for the steel cable, you would use:

a. both shear modulus and bulk modulus.

b. Young's modulus

c. bulk modulus.

d. shear modulus

e. both Young's modulus and bulk modulus.

Option (b)

Explanation:

As the actor swings on a steel cable, the cable stretches due to the weight of the actor. So, the stress produced by the weight of the actor is longitudinal stress and the strain is also longitudinal in nature.

The modulus of elasticity associated to the normal stress and the longitudinal strain is young's modulus.
