Gear z=12 (A)

The gear with $z=12$, where $z$ represents the number of teeth, is a precision-engineered component used in various machinery and mechanical systems. This gear plays a crucial role in transmitting rotational motion and torque between shafts. The number of teeth on the gear, in this case, 12, determines its engagement with other gears and its mechanical advantage. It is typically manufactured from high-strength materials such as steel or durable composites to ensure longevity and reliable performance under operational stresses. Proper alignment and maintenance of this gear are essential to prevent issues such as excessive wear or gear slipping, which can impact the efficiency of the entire mechanical system.
