A V-belt should ride in the groove near the ______ of the pulley without touching the ______.

Explanation:
The belt should seat in the groove in a way that uses the groove’s sides to create the wedge that transmits torque. Riding near the top of the groove lets the belt’s sidewalls press against the groove flanks, giving good friction and keeping the belt tracking properly in the pulley. If it moves toward the bottom, contact with the groove sides diminishes, increasing the chance of slipping and edge wear, and it may rub the bottom of the groove, leading to heat and premature belt wear. So riding near the top without touching the bottom provides stable tracking and efficient power transmission.
