The Discussion on Energy Loss on Conveyer Belt

描述了作用在传输带上的力对传输带上的沙做功的关系 ,得出了该力只有一半对沙做功 ,而另一半消耗在沙与传输带上的摩擦之中的结论。

This paper describes the relation between the force and work, in which the force is applied on the conveyer belt, and the work done by the forceis applied to the sand on the conveyer belt. The result is that only the force can do work and half of the force is wasted as the friction between the sand and conveyer belt.
