Mechanical advantage is a measure of the force amplification achieved by using a tool. This means the ideal mechanism does not include a power source.
This is called the mechanical advantage. and is just a ratio comparing how much you put in to how much you get out.

In physics and engineering, mechanical advantage(MA) is the factor by which a mechanism multiplies the force or torque put into it. Generally, the mechanical advantage is calculated as follows: or more simply:
A lever is a very useful tool that lets us exchange weight for distance. For example (theoretically) if you had to move a 200 pound sack into a car, but couldn't lift it, you could divide it into 8 parts, each being 25 pounds, and move each one individually into the car. It would be easy, however it would take more distance (lifting into the car 8 times instead of 1)
the equation of mechanical advantage isFout (force, output)divided byFin (force input)the equation for Ideal mechanical advantage isDin (distance, input)divided byDout (distance, output)hope this helps a bit
A mechanical advantage greater than one means that you have to put less effort into the system than if you had to do the work directly. Usually this is by spreading the effort you put in out over a longer distance or time. For instance, although in the end the same amount of work is done, lifting a box straight up with you hands is more difficult than using an inclined plane or lever to do the work.
That's the "mechanical advantage" of the machine.
the spring does not have a mechanical adavantage because the amout of force you put in to it is the amoot of force that the spring provides. The real mechanical is that you can time when the force is provided
If you get more force out of a machine than what was put into it, that is mechanical advantage. Levers and gears use this principal to amplify their output.
Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent). Efficiency = Useful Work Output ÷ Work Input
An advantage is that you will put more effort into the work. A disadvantage would be being hart broken if it doesn't work or the product fails.
