Force input= 8.5 and force output=73?billy_joule said:I'm not sure where you got that equation from but the normal form is:
MA = Force in / Force out
https://en.wikipedia.org/wiki/Mechanical_advantage
Can you find the MA now? If not, can you identify the force in and force out?
Ideal Mechanical Advantage (IMA) refers to the theoretical advantage that a machine has in amplifying the force applied to it. It is calculated by dividing the output force by the input force.
The IMA of a bicycle can be calculated by dividing the radius of the rear wheel by the radius of the front wheel. This is because the pedals, which are attached to the front wheel, rotate a larger distance than the rear wheel, resulting in a greater force being applied to the rear wheel.
The IMA of a bicycle can be affected by several factors, including the size and type of tires, the gear ratio, and the overall design and weight distribution of the bicycle.
Yes, the IMA of a bicycle can be increased by changing the gear ratio or using larger front and rear wheels. However, there may be trade-offs such as decreased speed or increased difficulty in pedaling.
The IMA of a bicycle is important because it determines the amount of effort needed to move the bicycle and how efficiently the force is transmitted from the pedals to the wheels. A higher IMA can make it easier to pedal and increase the speed of the bicycle, while a lower IMA may require more effort and result in a slower ride.
