Okay, I understand that I need to take the cross product of some moment of the wheels, but to be honest, I do not know which. Is it the angular momentum? In which case would 2d = r? and what about p?
I thought you knew that I don't know what that means because you said, "take moments" and I said, "I don't know what you mean by that."
I don't know what you mean by "moments".
Ʃf = μn1+ μn2
erg, sorry that's frictional. For normal force I would use
Ʃf = m1g+ m2g
Okay, so I guess I need to use the center of mass equation to figure out how much mass is over each roller?
Hi Tiny Tim!
If you don't mind, I'm going to try to think this one out on the board. You asked what are the two normal forces as a function of x? and so what is the net friction force as a function of x ?
Ok, so I know that depending on where x is, the normal forces of the wheels against the...
Homework Statement
Two identical rollers are mounted with their axes parallel, in a horizontal plane, a
distance 2d = 26.5 cm apart. The two rollers are rotating inwardly at the top
with the same angular speed (w). A long uniform board is laid across them in a direction
perpendicular to their...
