The ideal mechanical advantage is mechanical advantage calculated without using friction.
To calculate IMA for levers we neen to divide the input distance by the output distance. To find the input distance you need to measure the distance between the fulcrum to your effort force (thats your effort arm.) To find the output distance you need to measure the distance between the fulcrum and the load (load arm).
And to find the input distance of the inclined plane you need to look at the length of the effort distance and the output distance is simply the height.
The difference between the IMA and MA is that IMA is not using friction, so its calculated by using the distance.
