Unformatted text preview: EM 324 05/03/2008 13:07:00 1. Intro stress strain o definition, STE, Mohrs Circle o Stress-strain relationship (Hookes Law) 2. Axial effect sigma = P/A, deformation = PL/AE 3. Pressure Vessel Axial = 4. Today Torsional Loading definition twisting of a straight bar when loaded by torques (moments) that tend to produce rotation about the longitudinal axis. Convention for Torque? o Positive points out of the cut section. o Use right hand rule to determine direction of internal torque Assumptions o Always a circular shaft (solid or hollow) o Straight; constant diameter o Shearing strains are small o Plane section before twisting remains straight o o QuickTime and a TIFF (LZW) decompressor are needed to see this picture. focus on triangle ABB also focus on C (radius), point D (any arbitrary distance between B and the center No pull in the x-direction Epsilon-x = 0; deformation x = 0...
