1 of 1 A stepped shaft ABCD is subjected to three torques as shown in Figure 1. The torques have magnitudes of 4500 Nm, 3500 Nm and 2500 Nm. End A is fixed and the material is steel with shearmodulus of elasticity G= 80 GPa. Calculate the maximum shear stress of each segment in the shaft and the angle of twist at end Dif (0) (1) The shaft consisting of circular solid segments The shaft consisting of circular hollow segments with the thickness of each segmentis 10 mm 90 mm 2 m Motor A B 4500Nm 70 mm 1.5 m 75 mm 3500Nm 1.5 m Figure 1 2. When an electrical motor as shown in Figure 2 operates, it transmits 100 kW to the shaft at 17.5Hz. The gears at B, C and D drive a machinery requiring power equal to 100/2 kW, 100/3 kWand 100/6 kW, respectively. Calculate the maximum shearing stress in the shaft and the angleof twist dho between the motor at A and gear at Dif each shaft is hollow with 7.5 mm thick.Use shear modulus of 80 GPa.
