What results from a glaze on a belt, causing loss of power transmission?

A glaze on a belt typically refers to a smooth, shiny surface that forms when the belt has experienced excessive heat or wear. This glaze can significantly reduce the friction between the belt and the pulleys it drives. When friction is diminished, the belt cannot grip the pulleys effectively, leading to a loss of power transmission. This means that the belt will slip under load rather than transferring power efficiently, which can result in the system not functioning as intended.

In this context, the formation of a glazed belt directly leads to decreased performance and efficiency in power transmission. The other options, while they may relate to issues with belts, do not specifically describe the phenomenon of reduced grip due to surface sheen or smoothness that a glaze represents. Consequently, the correct response highlights the primary concern of the belt's surface condition and its direct consequences on performance.
