Final answer:
To determine the maximum allowable torque, use the formula T = (π/16) * τ * d^3, where T is the torque, τ is the shear stress, and d is the diameter of the shaft. The maximum allowable torque T is 169,646 N*mm. Without further information, it is not possible to determine the corresponding angle of twist between disk A and disk C.
Step-by-step explanation:
To determine the maximum allowable torque, we need to calculate the maximum allowable shear stress. The allowable shear stress for the 6061-T6 aluminum is given. We can use the formula T = (π/16) * τ * d^3, where T is the torque, τ is the shear stress, and d is the diameter of the shaft.
Substituting the values, we have T = (π/16) * 100 * (60 mm)^3. Solving this equation gives us the maximum allowable torque T = 169,646 N*mm.
For finding the corresponding angle of twist between disk A and disk C, we need to know the properties of the disk such as the torsional rigidity and the length of the shaft. Without this information, it is not possible to determine the angle of twist.
