Hi All,
I am working on a project that mounts an accelerometer to the bike pedal, and requires me to calculate the power that the sensor experiences as the bike is being ridden. However, I am having some trouble understanding the forces that the pedal/sensor experiences.
Essentially, I need to calculate power given the acceleration the sensor experiences, mass of the sensor, and time. Here's what I have right now:
Power = Work/time = ½*m*v^2
Power * Time = ½*m*v^2
v = sqrt(2*Power*t/m)
a = dv/dt = sqrt(Power/2*m*t)
Power = a^2*(2*m*t)
While this does give me power, I don't know if this equation is applicable to my project. I'm also thinking that I need to account for the rotational physics as well, which I am not sure how to do. Could someone explain how I could calculate the power at any given moment?
Thanks
