# Question Solved1 AnswerThe 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 (Yield strength = 67 Ksi, Ultimate strength = 80 Ksi). - Draw FBD of planes xy and xz (15 points) - Find bearing reactions (15 points) - Using The figure shows a shaft mounted in bearings at A and D and having pulleys at B and C.
