Question

What is the mechanical advantage of the lever?
3m and 6m
2
3
6
9

Answer 1

The mechanical advantage (MA) of a lever can be calculated using the formula:

\[ \text{Mechanical Advantage} = \frac{\text{Length of effort arm}}{\text{Length of load arm}} \]

In your case:

• Length of effort arm = 6 m
• Length of load arm = 3 m

Now, substituting these values into the formula:

\[ \text{Mechanical Advantage} = \frac{6 , \text{m}}{3 , \text{m}} = 2 \]

Thus, the mechanical advantage of the lever is 2.
