What does "overhang" indicate in a mechanical assembly?

In a mechanical assembly, "overhang" refers to the condition where a component extends beyond its intended support structure. This is significant because it can affect the stability and performance of the assembly. When a part overhangs, it may introduce imbalances or increase stress on the supporting components, leading to potential failure or decreased efficiency. Understanding overhang is crucial for engineers and designers to ensure that components are properly supported and that the forces acting on them are managed effectively.

The other choices do not accurately describe the concept of overhang. The weight of a component relates specifically to its mass and gravitational effects, while the speed of rotation pertains to how fast a component is turning, and the arrangement of gears deals with their configuration and interconnectivity. None of these aspects capture the important notion of components extending beyond their supports.
