How to Find the Mechanical Advantage of Simple Machines?
How do you know if the mechanical advantage is 1 (that’s more than one, one, and less than one, right?)
How do you find it without finding the actual mechanical advantage for the wedge, pulley, lever, wheel and axle, and inclined plane?
Your question is too broad for a practical answer.
For all MA calculations, you will have a load and an effort.
If the load exceeds the effort to move it, you have an advantage. If the load is less than the effort, you have a negative advantage.
If the load and the effort are identical, you have unity advantage.
You would ned to have the actual configuration of the items you want to find the MA of, including all the friction data, etc.
You have the “less” and “more” symbols reversed.
If the advantage is more than one (>1), you need less effort.
