Homework Problem 2: The state of stress in an element is shown below. The yield stress of the material is 16.8 ksi . Indicate whether the material will yield or not? Use Tresca and Von Mises yield surfaces. Comment on which criterion is conservative. Do not use the \( \tau_{\text {max }} \) equation as we used in class. Instead, draw the yield envelop and see if the principal stresses fall within the envelop.
