Answer:
D. 5
Explanation:
The mechanical advantage of the pulley is given by:
[tex]MA=\frac{F_{out}}{F_{in}}[/tex]
where
[tex]F_{out} = 650 N[/tex] is the output force exerted by the system
[tex]F_{in}=130 N[/tex] is the input force applied to the pulley system
Substituting the numbers into the equation, we find the mechanical advantage:
[tex]MA=\frac{650 N}{130 N}=5[/tex]
