Ok, I’ve remade the rubber band calculator! I’ll make a tutorial video soon, but I’ll make a simple explanation for now. Here’s what the different colored curves mean:
- RED: Actual force curve of a doubled up VEX #64 rubber band, X-axis = distance, Y-axis = force
- ORANGE: Distance between banding points, X-axis = angle, Y-axis = distance between points
- GREEN: Distance between banding points scaled by band curve, X-axis = angle, Y-axis = scaled distance between points
- PURPLE: Output force onto lift, X-axis = angle, Y-axis = force
The purple curve is most important curve, and this is the line you will focus on. If you want the same amount of force for the entire specified motion range on the lift, you want this to be completely horizontal between the pink lines. If you want less force at the very bottom of the lift (this allows you to have more lifting force overall while not having to force the lift down continuously while it’s at the bottom)
