Answer:
The ideal mechanical advantage of the bicycle is 0.25. This means that for every 0.25 meters you push down on the pedals, the rear wheel of the bicycle moves 1.0 meter, giving you a mechanical advantage of 0.25.
Step-by-step explanation:
The ideal mechanical advantage (IMA) of a machine is a measure of how much it amplifies force or distance. In the case of a bicycle, the pedals act as a lever, and when you push down on them, you exert a force. The rear wheel of the bicycle moves a greater distance for each rotation of the pedals.
The formula for calculating the ideal mechanical advantage (IMA) of a lever or simple machine is:
IMA = Distance moved by the input force / Distance moved by the output force
In this case, the distance moved by the input force is the distance the pedals move (0.25 meters), and the distance moved by the output force is the distance the rear wheel moves (1.0 meter).
IMA = 0.25 meters / 1.0 meter = 0.25
So, the ideal mechanical advantage of the bicycle is 0.25. This means that for every 0.25 meters you push down on the pedals, the rear wheel of the bicycle moves 1.0 meter, giving you a mechanical advantage of 0.25.
