Ay rero 0 02 2 2-11 casaw en convention Problem Statement Consider the pulley system shown, with pulley diameters da- 250, dB - 400 mm, and dimensions a 300,b -400,c 150 mm. The driving belts are under tension TI-187.5, T2-28.12, T3 45, T4-300 N, with θ-45°. The shaft is made of 1035 CD steel with Sy 460 MPa (Table A-20) We have calculated the reactions for you: Roy-157.9, Rcy-86.1, Ro119.8, R-91.47 N To complete this assignment, please do the following . Calculate the transmitted torque T, which is necessary to calculate the shear stressT. Draw (on paper) the shear-force and bending-moment diagrams for both planes r -y and r- z. At both points, A and B, calculate the net moment MA and MB by doing the vector sum of the two components, My and Mz, at the same point. For this you need the full diagrams. Further see which one of the net moments is the largest, which is necessary to calculate the bending stress σ Calculate the shaft diameter d required to get a safety factor n 2 using the MSS yield criterion Hint: The simplest interpretation of MSS is that the material yields when Tmaz - Sy/2 and, in this case, on the surface of the shaft Tmaz is simply the radius of Mohr's circle Answer tolerance = 2%). Be sure to include units and the correct sign with your answers. The sign of the bending-moment M and the
