What best describes a winch?

• A. A fixed hook used to suspend loads.
• B. A manual winch operated by hand.
• C. A torque wrench used to tighten bolts.
• D. A pulling tool with a chain or cable wound around a motor-driven drum, most commonly attached to the front, rear or side of a vehicle.

Answer: (D)

A winch is a pulling tool that uses a chain or cable wound around a motor-driven drum, typically mounted on the front, rear, or side of a vehicle to recover or move heavy loads. This definition covers the essential features: the cable or chain, the drum that winds it, the powered operation, and the common vehicle attachment for getting heavy loads under control. The other descriptions miss key aspects: a fixed hook describes a non-winding hook used to suspend loads, a manual winch is a subset that requires hand cranking instead of motor power, and a torque wrench tightens bolts, which isn’t about pulling loads.
