Question 1.
What is torsion?
Show hintHide hint
Think about how twisting a straw works.
Question 2.
What must be true about the angular displacement of a shaft fixed at both ends?
Show hintHide hint
Consider what happens when you twist something at each end.
3Question 3.
What is the primary consequence of applying torque to a shaft fixed at both ends?
- The shaft twists
- The shaft bends
- The shaft compresses
Show hintHide hint
Think about how torque affects a rotating object.
4Question 4.
True or False: The angular displacement at the fixed ends of a shaft must remain zero.
- True
- False
Show hintHide hint
What happens when ends are held firmly?
Question 5.
A circular shaft fixed at both ends experiences a torque of 200 N·m. If the shear modulus is 80 GPa and the polar moment of inertia is 30 × 10^-6 m^4, calculate the angle of twist.
Show hintHide hint
You might need the length of the shaft to solve fully.
Question 6.
Design a scenario where a shaft fixed at both ends would fail under excessive torque, outlining the reasons for its failure.
Show hintHide hint
Consider how material limits influence design choices.
