What is a "match number"?
What will be an ideal response?
Match numbers are used to exactly match up V-belts used in a multiple V-belt drive. A match number of 50 tells us that the V-belt is exactly the length it was designed to be. As the match number increases or decreases from the standard number of 50, the V-belt circumference increases or decreases.
