Unformatted text preview: logical r-theta system, we find that there is really only one component of stress, and that is in the theta direction (so no stress in the radial direction). This is written as: 3) Narrow Rectangular Cross sections a) The important condition here is that the top and bottom surfaces are traction free, so . Since, these faces are so close together (t is smll), we will assume that these are zero everywhere in the body. And if tau_yz is zero, so is dphi/dx. b) So. c) Note that warping is 0 along the entire centerline of the sheet....
