Which deformation method involves twisting of the object?

• A. Torsion
• B. Stability
• C. Momentum
• D. Impulse

Answer: (A)

Twisting about the object's axis is called torsion. When a torque is applied, different cross-sections of the object rotate relative to each other, creating shear strains that twist the structure. This deformation mode is what you observe when you twist a rod or shaft. The other terms describe different ideas: stability refers to balance and resisting tipping, momentum is the quantity of motion of an object, and impulse is the force applied over time that changes that momentum. So twisting is the specific deformation method associated with torsion.
