The mechanical advantage shown in the image is?

Answer:
3
Explanation:
The mechanical advantage of any machine is equal to the ratio between the output force and the input force:
[tex]MA=\frac{F_{out}}{F_{in}}[/tex]
In this problem, we have:
- Input force: 52 N
- Output force: 156 N
Therefore, the mechanical advantage is:
[tex]MA=\frac{156 N}{52 N}=3[/tex]
