Practice Problem 9-1 | Back | Index | Next |
Given: During mechanical testing, it is found that a certain steel machine part yields when under a stress state of s_{x} = 300 MPa, s_{y} = –100 MPa, and t_{xy} = 200 MPa. Assume plane stress conditions. Req'd: Based on the maximum shear stress theory (Tresca), determine the yield strength of the material, S_{y}. |
