If the parallel forces acting on a lever are in the ratio `3 : 5` then what is the mechanical advantage of the lever ?

Explanation

To find the mechanical advantage of a lever when the parallel forces acting on it are in the ratio of 3:5, we can follow these steps:

### Step 1: Understand the Concept of Mechanical Advantage
Mechanical advantage (MA) is defined as the ratio of the output force (F1) to the input force (F2) in a lever system. It helps us understand how much the lever amplifies the input force.

### Step 2: Identify the Given Ratio
The problem states that the parallel forces acting on the lever are in the ratio of 3:5. This means:
- F1 (the force exerted by the load) is to F2 (the effort applied) as 3 is to 5.
