Question

Explain how elastic hysteresis causes damage to a horse's leg.

Answer 1

I looked up elastic hysteresis and found that it is : the difference between strain energy required to generate a given stress in a material and elastic energy at that stress. It is the energy dissipated as heat in a material in one cycle of dynamic testing. I don't really understand can someone please help it to me?

Answer 2

Think of a string, when you elongate it too far it looses its shape, so you need some energy related to the elasticity, but you also need some energy to damage that string. What happens with the horse, is that it has a string, and if you elongate it too much, wich is not hard since the hysteresis is small, you damage the tendon. If you run for a long time, the problem is that the fibers of the tendon have diferent hysteresis and feel diferent stresses, so some of them always are damaged, so if you run too much, a lot of those fibers will brake and beyond the normal number.

Answer 3

So from what I can understand that the continued relaxing and contracting on a tendon will eventually cause it to snap. Thank you so much!!

Answer 4

Yes, but if used too much, it is natural that some fibers brake.

Answer 5

That sounded wrong, even using it correctly some fibers will brake.

Answer 6

Ok thanks I get what you mean :)
