I am writing an essay on the following. Can you look over what i wrote and help me edit or add to it. Not sure I answered the question. Thank you.

Explain in DETAIL how this hoist system works by taking each machine into account during the full cycle of cranking the lever arm back and forth once. Be sure to identify the contribution of each machine in the process. Be sure to explain theConservation of Energy, and how mechanical advantage allows you to"work smarter, not harder".

1. Crank the lever handle to one side (advance)

This is what I wrote so far.

Hoists are mechanical or electro-mechanical lifting devices that rely on mechanical advantage to move objects vertically and support hanging loads. Mechanical hoist equipment distributes weight by using pulleys or gears to transfer low force over long distances into larger forces applied over shorter distances. Mechanical advantages allow humans to perform tasks much easier in terms of the force they need to apply, but must always obey the conservation of energy. Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys. For example, you can calculate the theoretical mechanical advantage of a screw (a kind of simple machine) that is being forced into a piece of wood by a screwdriver. The actual mechanical advantage is much less than what is calculated because friction must be overcome in driving the screw into the wood.
