Required information A countershaft carrying two V-belt pulleys is shown in the figure. Pulley A receives power from a motor through a belt with the belt tensions shown. The power is transmitted through the shaft and delivered to the belt on pulley B. Assume the belt tension on the loose side at B is 15 percent of the tension on the tight side. Given: TA1= 500 lbf, TA2=75 lbf, da = 8 in, dg = 10 in, and dshaft = 1.25 in. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. One ΤΑΙ TA2 A(DA) 18 in dshaft B(dB) 12 in T₂ At the point of maximum bending moment, determine the principal stresses and the maximum shear stress. The first principal stress at the point of maximum bending moment is The second principal stress at the point of maximum bending moment is The maximum shear stress at the point of maximum bending moment is kpsi. kpsi. kpsi.
