Question

The stress on a wire supporting a load does not depend on?

Answer 1

a. wire’s length

b.wire’s diameter

c. mass of the load b.

d. acceleration of gravity

Answer 2

The stress on a wire supporting a load does not depend on the length of the wire.

• Strain is considered as the force exerted on a substance per unit area. When a material is stressed, it undergoes a change in dimensions known as strain. The strain-stress relationship is shown below.

                            Stress/Strain = γ

• In this, γ = the linear expansion proportionality
• The wire's length, the form of the cross-section of the wire, as well as the radius of the wire. don't really affect the strain of a body, as shown by the equation.
• However, stress is influenced by γ. Because γ  the breaking stress is now determined by the wire's substance, it is also determined by the wire's material.
• In layman's terms, it indicates that the breaking stress of two items composed of different materials will be different (the limit of strain the body can bear)
