The horse's leg.
A horse can run 50 kilometers per hour without using a lot of energy.The power from the body makes the leg push hard off the ground and it moves forward really quick.The calve on the leg is really large,and it makes the leg bend better and increases the speed.
The horse is an animal with four legs with very large thighs and if it kicks you,you could get a problem with your body and go to hospital.If it hits you hard enough it might kill you straight away.If the knee on a horse is broken the other legs wont gallop as well as before.
At one gallop the muscle in the leg acts like an shock absorber that takes energy so it wont break.A muscle tendon provides allot of agility and power.Engineers are trying to clone the horses leg so if a horse loses his leg there will be a robotic leg to attach.
How is this possible?
