While researching a topic, a student has taken the following notes:
• Generally, an object will heat up when twisted.
• The twisting of an object is known as torsion.
• A 2019 study led by Zunfeng Liu and Ray Baughman tested the torsional heating of various fibers.
• When a sample of thermoplastic polyurethane (TPU) fiber was twisted, its average surface temperature increased by 6°C.
• When a sample of single-ply nickel-titanium (NiTi) wire was twisted, its average surface temperature increased by 21.3°C.
