Question

A 3.0-meter long aluminum rod with uniform cross section is cut into a 2.0 m long piece and a 1.0 m long piece. Each piece supports a 650 n load. Which rod supports the greater tensile stress?

Answer 1

The tensile stress are the same in the both bits.

Step-by-step explanation:

Given that,

Load = 650 N

We need to calculate the tensile stress

Tensile stress :

Stress is equal to the force upon cross section area.It does not depend on length.

In mathematically form,

`tensile\ stress =(F)/(A)`

Where, F = load

A = area

Put the value into the formula

The tensile stress is

`tensile\ stress=(650)/(A)`

Force and area of cross section remains the same in both the bits.

Hence, The tensile stress are the same in the both bits.
