The solid shaft AE rotates at 500 rpm and transmits 45 kW from the motor M to the machine tools connected to gears G and H. Knowing that Tallow = 50 MPa and that 30 kW is taken off at gear G and 15 kW is taken off at gear H, determine the smallest permissible diameter of shaft AE. 100 mm 150 mm 200 mm 150 mm 75 mm 100 mm 100 mm

The A-36 solid steel shaft is 2 $\mathrm{m}$ long and has a diameter of $60 \mathrm{mm} .$ It is required to transmit $60 \mathrm{kW}$ of power from the motor $M$ to the pump $P .$ Determine the smallest angular velocity the shaft can have if the allowable shear stress is $\tau_{\text {allow }}=80 \mathrm{MPa}$
Gear $B$ supplies $15 \mathrm{kW}$ of power, while gears $A, C$ and $D$ withdraw $6 \mathrm{kW}, 4 \mathrm{kW}$ and $5 \mathrm{kW}$, respectively. If the shaft is made of steel with the allowable shear stress of $\tau_{\text {allow }}=75 \mathrm{MPa},$ and the relative angle of twist between any two gears cannot exceed 0.05 rad, determine the required minimum diameter $d$ of the shaft to the nearest millimeter. The shaft is rotating at 600 rpm.
