Question

how can you gain max. mechanical advantage in terms of fulcrum and effort? place them close together place them far apart placement doesnt matter none of these

Explanation:

The formula for mechanical advantage (MA) of a lever is \(MA=\frac{\text{Load arm}}{\text{Effort arm}}\). To gain maximum mechanical advantage, we need to maximize the load arm and minimize the effort arm. This is achieved by placing the fulcrum and effort as far apart as possible.

Answer:

place them far apart
