Re: How Do mecanum wheels handle the bumps?

You've agreed that the mechanum has seperate and equal sideways and forward forces, and the disagreement is what the total force is, as well as each seperate force (which would each follow from the other).
Can we also agree that the total force is a seperate force*(sqrt)2?
I'd also like to resuggest the idea of 60 degree mechanums. It was suggested they would still have 10 lb. forward force, with a lesser sideways force. What if you mounted 30 degree mechanums perpendicularly? With the rollers at the same angle, shouldn't forces be the same? The constant 10 lb. forward force model wouldn't work if I'm correct.
I've taken only basic physics (I do understand vector math), so feel free to correct me if I'm way off here.
