Question 2: For the Aluminium shaft shown in Figure 2 with "Shear Modulus (G) = 27 GPa", determine The Torque T that causes an angle of twist of 4º. (a) (b) The angle of twist caused by the same Torque T in a solid cylindrical shaft of the same length and cross-sectional area. T 12 mm 1.25 m 18 mm

The torsional assembly shown in the figure consists of a solid 60-mm diameter aluminum [G = 28 GPa] segment (2) and two bronze [G = 45 GPa] tube segments (1) and (3), which have an outside diameter of 75 mm and a wall thickness of 5 mm. If concentrated torques of TB = 9 kN-m and TC = 9 kN-m are applied in the directions shown, determine the following: 1. Calculate the polar moment of inertia of the bronze tube in mm^4. 2. Calculate the polar moment of inertia of the aluminum tube in mm^4. 3. Calculate the internal torque in the aluminum segment in kN.m 4. Calculate the internal torque in the bronze segment in kN.m 5. Calculate the maximum shear stress in bronze tube segments in MPa. 6. Calculate the maximum shear stress in aluminum tube segment in MPa. 7. Calculate the absolute value of the angle of twist of bronze tube in radian. 8. Calculate the absolute value of the angle of twist of aluminum tube in radian.   Kindly answer all questions with complete solution please

A shaft of diameter 30 mm is to be used to transmit a torque. The shaft is manufactured from a material with a shear strength 86 MPa. Calculate the maximum torque the shaft can carry. Provide your answer in Nm to at least one decimal place.
