1. The problem statement, all variables and given/known data I think I've solved this properly, but if you guys wouldn't mind verifying my work and pointing out any errors (if there are any), it would be much appreciated. http://img391.imageshack.us/img391/6520/problemvm0.jpg [Broken] I've already calculated the equivalent force-couple system at the plane of the elemental stress block, which is shown above. That's completely right, I know of it :). Now, I need to solve for the components of normal and shearing stress associated with that elemental stress block. 2. Relevant equations [tex]\sigma[/tex]Axial = P / A [tex]\sigma[/tex]Bending = Mc / I [tex]\tau[/tex]Shear = VQ / IT [tex]\tau[/tex]Torque = Tc / J We already are given: A = 12.57 in^2 J = 25.13 in^4 I = 12.57 in^2 Q = 5.33 in^3 D = 4 in 3. The attempt at a solution Using the equations above, I've calculated: [tex]\sigma[/tex]Axial = 477.46 psi [tex]\sigma[/tex]Bending = 12,414.09 psi [tex]\tau[/tex]Shear = 106.10 psi [tex]\tau[/tex]Torque = 5729.58 psi Did this all with excel :). Do those answers sound right? The next step which I am having difficulty with is calculating the [tex]\sigma[/tex]X, [tex]\sigma[/tex]Y, and [tex]\tau[/tex]XY. I understand that I'm just using super position for this, but I'm not sure whether to add or subtract the two. Thanks!
