The strength of the arms to withstand vertical and horizontal forces is known as what?

Explanation:
Force resistance describes how well the arms can carry and transfer the loads that act on them, both vertical and horizontal. This is crucial because gravity, dynamic forces from movement, and lateral pushes from the car and passengers all load those arms. A strong force resistance means the arms won’t deform or fail, keeping the system safe and aligned during operation. The other terms refer to different functions: obstruction devices detect objects in the path to stop the escalator; manual unlocking is a maintenance action to disengage the drive; winding drums are part of the drive system that wind and unwind the chain.
