Answer:
IMA = 3
Explanation:
Given the following data;
Distance covered by the effort or output distance = 120 m
Distance covered by the load or input distance = 40 m
To find the ideal mechanical advantage (IMA);
Mathematically, IMA is given by the formula;
[tex] IMA = \frac {distance \; over \; which \; the \; effort \; is \; applied}{distance \; the \; load \; travels} [/tex]
Substituting into the equation, we have;
[tex] IMA = \frac {120}{40}[/tex]
IMA = 3
Therefore, the ideal mechanical advantage (IMA) of this ski lift is 3.
NB: The ideal mechanical advantage has no units.
