Problem
A student tightens three identical bolts using the same wrench so that the magnitude of the applied torque is the same in every case. Bolt A is turned through 90∘, bolt B through 180∘, and bolt C through 270∘. Rank the bolts according to the work done on them, from greatest to least.
(a) A=B=C
(b) C>B>A
(c) A>B>C
(d) A=C>B
