6-33* The motor shown in Fig. P6-33 develops a torque $T=$ $1500\mathrm{lb}?\mathrm{ft}$; the output torques from gears $C$ and $D$ are equal. The mean diameters of gears $A$ and $B$ are 12 in. and 4 in., respectively. If the diameter of the motor shaft is 2 in. and the diameter of the power shaft is 1.25 in., determine a. The torque in the power shaft between gears $B$ and $C$. b. The torque in the power shaft between gears $C$ and $D$. c. The maximum tensile and compressive stresses in each shaft. Figure P6-33 (a) $T_{BC}=500\mathrm{lb}?\mathrm{ft}$ (b) $T_{CD}=250\mathrm{lb}?\mathrm{ft}$ (c) ${?}_{\max }$ (motor) $=11.46\mathrm{ksi}$ ${?}_{\max }($ motor $)=11.46\mathrm{ksi}(\mathrm{T})\&(\mathrm{C})$ (d) ${?}_{\max }($ power $)=15.65\mathrm{ksi}$ ${?}_{\max }($ power $)=15.65\mathrm{ksi}(\mathrm{T})\&(\mathrm{C})$
