Given:

input force is


485\text{ lb}

output force is


2800\text{ lb}

Required: calculate mechanical advantage

Step-by-step explanation:

to calculate the mechanical advantage of this jack

we will use formula that is given by


Mechanical\text{ force advantage=}\frac{load(output\text{ force\rparen}}{effort(input\text{ force\rparen}}

plugging all the values in the above relation we get:


\begin{gathered} mechanical\text{ force advantage=}\frac{2800\text{ lb}}{485\text{ lb}} \\ =5.77 \end{gathered}

Thus, the mechanical advantage of this jack is 5.77.
