Question 1
An engineer must design a shaft for a motor. If the shaft has three sections with respective torques of 200 Nm, 150 Nm, and 100 Nm, lengths of 0.5 m, 0.7 m, and 0.4 m, shear moduli of 80 GPa, 100 GPa, and 75 GPa, and polar moments of inertia of 0.0004 m^4, 0.0006 m^4, and 0.0002 m^4, calculate the total twist.
💡 Hint: Ensure unit consistency when calculating.
Question 2
Discuss the design changes needed if the boundary conditions of one segment change from fixed to free.
💡 Hint: Consider material fatigue and safety factors.
