\( 7.70 \) and \( 7.71 \) For the state of stress shown, determine the maximum shearing stress when \( (a) \sigma_{z}=+24 \mathrm{MPa},(b) \sigma_{z}=-24 \mathrm{MPa},(c) \sigma_{z}=0 \).
Expert Answer
For Figure ?7.70 ? ?x = 30 MPa, ?y = 60 MPa, ?z = 24 MPa, ?xy = 36 MPa [30, 36, 0] [?] = [36, 60, 0]
