« on: February 24, 2007, 08:18:34 PM »
I need help with 2 formulas that are in layman's terms so that I can use in a spread sheet to solve the following problems. I am not familiar with all the terms and symbols used in physics mathematics.
 
formula 1
An an axle having 1 spoke with a movable weight   I need to be able to calculate the ft/lbs of torque, energy produced and speed in  any given degrees of rotation.

Using the following as variables:
SL Spokes length
SW Spokes weight
MW movable weight
DW distance of weight on the spoke from axle
SP dergee of starting point
DR degrees of rotation
V speed of rotation
 
Example: a 4 foot spoke weighing 10 pounds with a 20 pound weight placed 1 foot from the axle with a starting point of 30 degrees  rotates 30 degrees at 32ft/2^2 producing ___ ft/lbs of torque and ___ kw energy
 
 
formula 2
 
foot/pounds of torque and energy required to lift a weight using gears and a pulley

using the followin as variables:
W weight
D distance lifted
DR degrees of rotation
V speed of rotation
 
Example:  10 pounds lifted 4 feet in 30 degrees of rotation of an axle with a rotational speed of 32ft/2^2 requires ___ ft/lbs of torque and uses ___ kw energy
 
Thanks for any help anyone can give some me
