    What Forces Act on a Chainring During Cycling?

    Thanks you so much to all your help Merlin3189!

    What Forces Act on a Chainring During Cycling?

    My interpretation was that 1273N was found using a constant torque applied to the pedal (at 1000 Watts/100 rpm). Since I'm assigning 1000 Watts/100rpm in my question as the Maximum Power Output (not an average), this 'average' of 1273N on the chain would actually be at Peak...Thinking like if we...

    What Forces Act on a Chainring During Cycling?

    Merlin3189, Quick last check: I've started using 1273N as my resulting number for my experiment...but after reading your message again, for some reason got me confused. 'My opinion is that the force varies roughly as a sine function. If the rider is applying a vertical force on the pedals, then...

    What Forces Act on a Chainring During Cycling?

    Thank you all. Yes, I am interested on the peaks. Another consideration of mine is how the Chainring is configure: For example, a ring connected to a 104 BCD Spyder have a different approach on the numbers needed to find these forces. A direct mount ring (Spyderless) is one single part, and the...

    What Forces Act on a Chainring During Cycling?

    Wow...thanks Merlin! Let me think better through your feedback, that's awesome! I guess I can rewrite my final question: it's not the interaction to the teeth itself, my question is more on what is the final torque applied to the chairing from from perimeter to the center...now I'm thinking...

    Thanks Mark. I am trying to find threshold limits for material fatigue, so the math needs to be done and maximum load position.

    What Forces Act on a Chainring During Cycling?

    Ok, New to the forum! I'm rusty in Physics but I'm trying to find this answer...part of a personal project. I'm trying to find the forces involved during cycling, specifically related to the Chainring (Crank), What numbers do I need to know to find this force? Let's say I have: -Maximum...
