Q1 (b): A cold-drawn solid steel shaft is driven at N=287 RPM carries two gears D and E, as shown in the figure. Gear D has an input power of P,= 9 kW, while gear E gives an equal output power. For a factor of safety of n=2.5, design the shaft according to the following failure criteria: Assume Sy 309 MPa, Sut 598 MPa, K=1.4, Ks=1.4 15 kg 15 kg y 0.4 m 0.6 m 0.4 m Calculate the mean torque, Tm in N.m units upto 4 digits after decimal. Enter only numeric value without units. Assume k = 0.81 and the shaft is operating at room temperature of 70°F with 50% reliability.
