Problem 4. Two solid shafts are connected by rigid gears as shown. A torque T-1200 Nm is applied on shaft AB as shown. Determine: (a) the force between the two gears, (b) the torque in the shaft CD and the reaction of the fixed support D. (c) the angle of rotation of section C, (d) the angle of rotation of the bottom gear, (e) the angle of rotation of section 4, (f) the maximum sheer stresses in the shafts AB and CD. T = 1200 Nm A R = 240 mm G=77.2 GPa d=42 mm 1-1.6 m B C |=12m G=77.2 GPa R = 80 mm dcp=60 mm D
