According to the laws of physics, output force (F) times output distance (D) equals output work (W).
W = F x D
The mechanical advantage (MA) is calculated as the ratio of the output force to the input force, or the distance the input force acts over compared to the distance the output force moves. The formula for mechanical advantage is MA = output force / input force = input distance / output distance.
force output x distance = work output ~same for input
It would be 12 plus the other number with a minus of 7. Then you would add the energy with the force and get something along the lines of a wrong answer because i have no idea what im doing.. Hope that helps
The quantity that measures how much a machine multiplies force or distance is known as mechanical advantage. It is calculated as the ratio of the output force to the input force, or the ratio of the input distance to the output distance in a machine.
If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.
input distance- the distance the input force acts through
Output distance is.
force output x distance = work output ~same for input
That means that if you use a simple machine to apply less force, you need to compensate by applying the force over a larger distance - for example, to lift up a weight or do some other work.
The equation for ideal mechanical advantage is: Output force/input force, Or input distance/ output distance.
Distance moved by input force / distance moved by output force
If a simple machine provide an increased output force, then the the distance from the load to the pivot needs to be increased.

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
Because the output distance is always greaterthan the input distance,and the product of (force) x (distance) is nearly the same on both ends.
