COld-arawn solld steel shaft is driven at N= 295 RPM carries two gears D and E, as shown in the figure. Gear D has an input power of P,= 11 kW, while gear E gives an equal output power. For a factor of safety of n=2.2, design the shaft according to the following failure criteria: Assume Sy 291 MPa, Sut=597 MPa, K=1.3, Kfs=1.4 15 kg 15 kg E 0.4 m 0.6 m 0.4 m Calculate endurance limit, Se, in MPa units assuming all the Marin factors are unity. Enter only numeric value without units. Assume k=0.77 and the shaft is operating at room temperature of 70°F with 50% reliability.
