"twist"의 '명사형' 동의어 (1).
1.
Which situation best illustrates the concept of torsion?
A) A ribbon curled into a spiral
B) A rod twisted due to applied torque
C) A wire looped into a circle
D) A spring coiled around a pencil
Correct Answer: B
Explanation:
Torsion refers to the mechanical twisting of an object,
especially in structural or physical contexts.
Unlike general coiling or looping,
it involves stress and torque applied to a solid object.
2.
Which of the following best describes a curl?
