Dear Brian22 most of the time in mechanical we create the system in critical condition and then we calibrate system in the real condition that work.
I want, I can, I do.
I think its better you run a system in a dynamic model and then try to find the forces and after that you create the control system.
then run it in the real state by virtual masses and calibrate your system.
And I agree with BrianE22 in other wise its really dangerous!!
I want, I can, I do.
excuse me I don't think like you, I think you need the friction between chain and Sprocket wheels, the wheels and the rails and the critical point of your motion somewhere you need most of your power!
so on I think the weight is not enough!
I want, I can, I do.
I think your description is true.
and I think the difference is in their way of control.
thanks a lot for your help
be congratulate
I want, I can, I do.
thanks rb1957
I think like you but the mater is that in some articles I've red they have different ways to make change in direction.
Some one told me the CMG use moment vector and reaction wheels use reactions of motion?!
I want, I can, I do.
