Bicycle Definition and 308 Threads

Hi guys.. I am a new member of physicsforums.com (I am a science student at the pre-undergrad level). I am unable to solve a problem involving motion of a chain along a circular track, in classical mechanics. The problem is from an old book on mechanics. Please read the problem (below) and...

Hello, Typical bicycle wheels have 36 spokes that are trued to a final tension of roughly 200 pounds. If a pair of adjacent spokes are squeezed together with one hand with a force of roughly 100 pounds, what does the spoke tension rise to? I'm asking because this healthy-squeeze...

Hi guys, I'm from a site/forum dedicated to riding called http://www.alwaysmad.com/cgi-bin/ikonboard/ikonboard.cgi?act=Portal. We currently have a a bit of a debate going and I thought you guys might have a clear and confirmed answer. The question is this: Thanks in advance for any...

A bicycle has wheels of 1.2m diameter. the bicyclist accelerates from rest with constant acceleration to 24km/h in 14.0s. What is the angular acceleration of the wheels? If the bicycle is going forwards relative to the ground with a speed of 24km/h, then, all points on the tread are moving...

Hello, I just found this place and I am glad I did. :D I have a big physics project and I need to relate bicycle to physics. I am in grade 11 and I was wondering if anybody can give me some ideas/suggestions on what kind of things I can relate physics to bicycle using up to grade 11 physics...

bicycle tires question... ok...heres a question that was given in the interview to a student who wanted to study physics at cabridge university. why when there is air loss in the tires of a bicycle(pressure decrease)...the bicycle becomes(heavier)?,meaning...harder to cycle.

A cyclist and her bicycle have a combined mass of 75 kg. she coasts down a road inclined at 2.0 degrees with the horizontal at 4.0 m/s and coasts down another road inclined at 4.0 degrees at 8.0 m/s. she then holds on to a moving vehicle and coasts on a level road. what power must the vehicle...

In Ireland, 16 year olds are expected to answer this question at some point during the leaving cert physics course. I’m finding it difficult to answer. Can anyone help me here? Ah, nothing like sharing wisdom... The rear of a bicycle passes a point P on a road and travels at a steady speed of...
