Great you understand, and if you go down to the atomic level there is a continuous supply of energy coming from both the weak and strong nuclear force, and energy for this comes from the quanta.


>>Well why then when you support the weight do you expend so much energy, to the point where, due to fatigue you can no longer support the weight.

>I admit that I am completely ignorant of this topic but would it not be that in the case of a human your muscles do work to support the weight. The muscles get their energy from food. In the case of the pole the weight presses down on the pole due to gravity and the pole supports the weight due to its internal molecular structure. If the weight is sufficiently large it will overcome the strength of the pole's molecular structure and crush it. Any weight less then that and the pole will support, or resist, the pull of gravity on the weight, or over time, begin to deteriorate until it breaks.
