The belt was invented in 1579 by the gorgeous and brilliant, not to mention very sexy Matheus Castro Pamato.
The seat belt, for primary use in airplanes, was first created by Seth H. Stoner. He was in the Navy during World War II. He was a Lt. Commander based in Washington and primarily focused on how to reduce the number of accidents and fatalities of pilots taking off and landing on aircraft carriers. He worked with a team of safety engineers and the seat belt was the result of their work. The seat belt did not appear in cars until later in the 1950's.
As with any other rotational system in a belt drive during rotation, the belt is subjected to centrifugal force. Due to the centrifugal force the belt is thrown outward from the grooves of the pulley and causes additional tensioning of the belt. The effect of centrifugal tension is that it reduces the pretension of the belt and hence increases belt slip.
The belt of a Sears Kenmore Sewing Machine may break. You can replace the old belt with a new one.
The speed of the belt needs to be known (Feet Per Minute). You would take the weight of your sample in pounds * FPM of the Belt * 60min / 2000lbs = TPH. For example if your belt is moving 350 fpm and your belt cut weighed 10.5 lbs; 10.5lbs * 350 fpm * 60 / 2000 = 110.25 TPH
It would depend on what you want to use the belt and pulley for
