Given: During mechanical testing, it is found that a certain steel machine part yields when under a stress state of sx = 300 MPa, sy = –100 MPa, and txy = 200 MPa. Assume plane stress conditions.

Req'd: Based on the maximum shear stress theory (Tresca), determine the yield strength of the material, Sy.

Sy =
