Determine Wall Thickness for 1,000 in. Aluminum Tube to Support 10-kip Load

[thall88]

An aluminum tube with an outside diameter of 1,000 in. will be used to support a 10-kip load. If the axial stress in the member must be limited to 30 ksi T or C, determine the wall thickness required for the tube. I used tau=shearing stress/area therefore 30(pie times 1-d)=10 but that is not correct Thanks

I believe the question refers to normal stress $\sigma$

Also remember that stress divided by area is not what you want. You want LOAD divided by area to get stress.
