Transcribed Image Text:3. 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. Using a conservative failure theory with a design factor of 2, determine the minimum shaft diameter
to avoid yielding.

4. By modern standards, the shaft design of problem 3 is poor because it is so long. Suppose it is redesigned
by halving the length dimensions. Using the same material and design factor as in problem, find the new
shaft diameter.
