A 1 .0 -in.-diameter hole is drilled on the centerline of a long, flat steel bar that is 1 2 thick and 4 in. wide. The bar is subjected to a tensile load of 3 0 , 000 lb. Calculate the average stress in the plane of the reduced cross section and the maximum tensile stress immediately adjacent to the hole.

Can you help me with this problem?
A tube from aluminium with an outside diameter of 50 (mm) and a wall thickness of 5 (mm) is used as a compression member. If the axial normal stress in the member must be limited to 90 MPa, what is the maximum force (in kN) that the member can support.
