What is the mechanical advantage of the class 1 lever?

Question

Input = Effort

Output = Load
picture shows a seesaw with 60n effort on left and 360n load on the right

a
.00138
b
60
c
216
d
6
e
21,600

Answer 1

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

\[ \text{MA} = \frac{\text{Load}}{\text{Effort}} \]

In your example, you have:

• Load = 360 N
• Effort = 60 N

Plugging in the values:

\[ \text{MA} = \frac{360 , \text{N}}{60 , \text{N}} = 6 \]

Thus, the mechanical advantage of the class 1 lever is 6.

The correct answer is d. 6.
