Answer:

IMA = 0.25

Step-by-step explanation:

Given the following data;

Input distance = 1m

Output distance = 4m

To find the ideal mechanical advantage;

Mathematically, IMA is given by the formula;


IMA = \frac {distance \; over \; which \; the \; effort \; is \; applied}{distance \; the \; load \; travels}

NB: The ideal mechanical advantage has no units.

Substituting into the equation, we have;


IMA = \frac {1}{4}

IMA = 0.25

Therefore, the ideal mechanical advantage (IMA) of this bicycle is 0.25.
