In Reply to: Best way to calculate torque through an angle of rotation? posted by Vector Viper on January 24, 2003 at 01:11:42:
: I realize 1 foot pound of torque is a 1 pound weight one foot
: from an axle, but only at 90 degrees (horizontal to ground)
: How can I find the average torque on an axle of a weight,
: say moving from 0 to 180 degrees
: (straight up to straight down) ?

Again I believe you are working on a machine similar to the one I am working on. In mine if there was no friction and each weight worked equally it would rotate with about 16 foot pounds of usable torque. It starts like a cold jar of molasses and then stops, if I help it past the small dead zone it will continue until it reaches it's dead zone again. The problem I'm having is that the weights don't react equally and they don't go from mode "A" to mode "B" 100%. I knew that they would'nt be 100%, some are 45% and other ones about 40% efficient. If I could build a heavy flywheel or a second machine I could couple it with the dead zone out of phase to achieve perpetual motion. As it is it's like an electric motor with a bad communicator.
And for your question, A simple way to find torque using two or more levers. When the angle of the second lever changes, the
weight on the scale changes. Divide the total reading by the number of levers for the average torque. See a diagram here http://home.gci.net/~rflory/torque.jpg Let me know what you come up with.
Hope it helps,
Ron
