Which term describes a distortion in which the ends of a material do not lie on the same plane?

Which term describes a distortion in which the ends of a material do not lie on the same plane?

• A. Toughness
• B. Twisting
• C. Volume
• D. Transparency

Answer: (B)

Twisting describes distortion due to torsion, where different cross-sections along the length rotate relative to each other. As a rod is twisted, these rotations accumulate so the ends no longer lie in the same plane, causing a non-planar alignment. The other terms don't describe this behavior: toughness is about energy absorption before failure, volume is a size measure, and transparency is about light passage.
