mmmmm let's see! i now know the kinetic energy of the wheel, and by calculating the energy required for one revolution, i can calculate the maximum possible number of revs, thus the maximum possible distance, without friction. i need the find the coefficient of rolling friction for wood on...

Homework Statement this is not really a homework question, but it would make a good one!. i posted it in the classical mechanics forum, but did not seem to get much help i have a two wheel rims, 50mm thick, (ouside radius 500mm, inside 475mm) connected by 8 horizontal spokes. between two of...

ahh, unfortunately i do not have any grounding in physics (bar what my internet research has taught me!). I know that friction is what is going to bring the wheel to a halt, but i don't know how to work out what the friction is. i assume that once i know the friction, i can use it with the...

i have a problem regarding rolling wheels. ihave a double wheel rim connected by spokes, which is in perfect balance, with two baskets hanging between them, on opposite sides of the wheel, such that when a weight is added to the top basket the wheel will rotate, dropping the basket at the bottom...
