Given:
input force is
[tex]485\text{ lb}[/tex]output force is
[tex]2800\text{ lb}[/tex]Required: calculate mechanical advantage
Explanation:
to calculate the mechanical advantage of this jack
we will use formula that is given by
[tex]Mechanical\text{ force advantage=}\frac{load(output\text{ force\rparen}}{effort(input\text{ force\rparen}}[/tex]plugging all the values in the above relation we get:
[tex]\begin{gathered} mechanical\text{ force advantage=}\frac{2800\text{ lb}}{485\text{ lb}} \\ =5.77 \end{gathered}[/tex]Thus, the mechanical advantage of this jack is 5.77.
