Question 3276 Deck General

The correct answer is B) Gearwheel. In a jacking system, a pinion is the smaller of two gears that meshes with a larger gear, known as the rack. The pinion is a gearwheel that engages with the rack to provide the mechanical advantage needed to lift or lower the load. This is a key component of the jacking system's design and operation. The other answer choices are incorrect because they do not accurately describe the function of a pinion in a jacking system. A flexible joint, flexible shaft, or flexible coupling are not the same as a pinion gear.
