If the mechanical advantage of a lever is 2.5, what will be the effort you need to apply to lift a load of 50 N?

Explanation

To solve the problem, we need to find the effort required to lift a load using the mechanical advantage of a lever. Here’s a step-by-step solution:

### Step 1: Understand the formula for Mechanical Advantage (MA)
The mechanical advantage of a lever is given by the formula:
\[ \text{MA} = \frac{\text{Load}}{\text{Effort}} \]

### Step 2: Identify the given values
From the question, we know:
...
