The figure shows a shaft mounted in bearings at A and D and having pulleys at B and C. The forces shown acting on the pulley surfaces represent the belt tensions. The shaft is to be made of AISI 1035 CD steel. The design factor is 2. The value of FB1= 310 lb, FB2= 51.667 lb, FC1= 61.039 lb, and FC2= 405.549 lb. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 6-in D. FB1 FB2 FC2 FC1 D 6 in 8 in 8-in D. 8 in Determine the values of the reaction forces. The reaction force at A in y direction is 127.251 lb. The reaction force at D in y direction is 339.336 lb. The reaction force at A in z direction is 230.151 lb. The reaction force at D in z direction is 131.515 lb.
