Question

Axial loads are applied with rigid bearing plates to the solid cylindrical rods shown.

The diameter of the aluminum rod (1) is 2.00 in. the diameter of the brass rod (2) is 1.50 in. and the diameter of steel rod (3) is 3.00 in.

Determine the axial stress is each of the three rods.

Answer 1

To find the stress you need to know the applied load. Without that information, it is not possible to determine the axial stress in each of the three rods.

Step-by-step explanation:

To determine the axial stress in each of the three rods, you would need to know the applied load and the cross-sectional area of each rod. The formula for axial stress is:

Stress (σ) = Load (F) / Area (A)

The area of a rod can be determined using the formula:

Area = π * (diameter/2)^2

Where diameter is the diameter of the rod in inches.

So,

For rod 1(aluminum rod)

Area = π * (2.00/2)^2 = 3.14 in^2

For rod 2(brass rod)

Area = π * (1.50/2)^2 = 1.77 in^2

For rod 3(steel rod)

Area = π * (3.00/2)^2 = 7.07 in^2

To find the stress you need to know the applied load. Without that information, it is not possible to determine the axial stress in each of the three rods.
