Mechanical power can be very interesting. The reason I say that is because mechanical power can take a certain amount of energy and only take what it needs. Even though mechanical machines have unlimited motions, these motions are transmitted in three ways,with, links, gear, and connections. They're called linkages or gears such as a gear of a bicycle or the chain of a bike, and finally connections such as chains and ropes. All in all, mechanical machines are very fascinating in the way they work.
Electrical machines are another wonderful type of machine.
Their source of power is electric powered by the smallest source called electrons. Next, electrons are tiny particles within atoms that each have a minute amount of an electrical charge. Last, when electric currents flow through a wire, there are an unbelievable high number of particles. The next source of power is Fluid power. Fluid power uses water and other liquids.
