Nathalie pushes on the pedals of his bike with a 320N force. If the bike has a produced force of 640N, what is the mechanical gain of the bike?

Gain = output/input

To find the mechanical gain of the bike, we need to divide the produced force by the applied force.

The applied force provided by Nathalie on the pedals is 320N, and the produced force of the bike is 640N.

Therefore, the mechanical gain of the bike can be calculated as:

Mechanical Gain = Produced Force / Applied Force

Mechanical Gain = 640N / 320N

Now, we can do the calculation:

Mechanical Gain = 2

Hence, the mechanical gain of the bike is 2.
