A V-belt should ride __________ in the groove with its top near the top of the sheave, and does not touch the __________ of the sheave.

A V-belt should ride high in the groove with its top near the top of the sheave, and it should not touch the bottom of the sheave. This positioning is important because it ensures that the belt is properly aligned and maintains optimal tension during operation. When the belt rides high, it effectively engages with the sheave to transmit power efficiently while minimizing wear and potential slippage. Ensuring that the belt does not touch the bottom of the sheave prevents unnecessary friction and damage that could lead to premature failure of both the belt and the sheave. Proper alignment and positioning help maintain the longevity and effectiveness of the drive system.
