TA TB Tc Therefore we have the equation for equilibrium: TA + Tp = 0.7 KN-m And the equation for compatibility: PAB + PBC + PCD = 0 That is: -TA x 2 + (-TA + 1.2) x 4 + To X 4 = 0, so we can solve (rounded to 0.01): TA = 0.76 KN-m, To = -0.06 KN-m, Correct! please scroll down (Note: answer in degrees, round to Since PE = PAB + PBE Thus we have pe = (-TA * TAB + (1.2 - TA) IBE) / (G X J) = -0.87 0.01) Correct! please scroll down MPa (round to 0.01) Finally, please calculate the maximum shear stress Tmax = Tmax C/ J: Tmax = 6.55 Check
