The drive shaft of the motor is made of a material having an allowable shear stress of $${?}_{\text{allow }}=72\mathrm{MPa}$$. the shaft is operating at an angular velocity of $$1700\mathrm{rev}/\min$$. Take If the motor is to deliver a power of $$25\mathrm{kW}$$, determine the required minimum outer diameter of the tubular $$c_i=0.75c_o$$ shaft to the nearest $$\mathrm{mm}$$. (Figure 1) Express your answer in millimeters. $$d_0$$ $$\mathrm{m}$$ Figure 1 of 1 X Incorrect; Try Again; 2 attempts remaining Part B Determine the required corresponding inner diameter of the tubular shaft to the nearest $$\mathrm{mm}$$. Express your answer in millimeters.
