Question 3273 Deck General

The correct answer is A) Sheave. A grooved pulley, also known as a sheave, is a wheel or disk with a grooved rim used to support and guide a rope, cable, or belt. The grooved rim allows the rope or cable to sit securely in the pulley, preventing it from slipping or sliding off. This design is commonly used in mechanical systems, such as those found on ships and boats, to efficiently transmit power or change the direction of a moving line. The other answer choices are incorrect because they do not accurately describe the specific component of a pulley system known as a grooved pulley or sheave.
