Problem $05\mathrm{.}076-$ Calculating the minimum diameter of a shaft

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 $F_{B1}=200lb,F_{B2}=33\mathrm{.}3lb,F_{C1}=39\mathrm{.}4lb,$ and $F_{C2}=261\mathrm{.}6lb.$
