Solving Dynamics Problem: Angular Momentum & Force

[ribeiro.rob]

Homework Statement

I am currently working a project which involves a spinning mass. The spinning of this mass will generate angular momentum which needs to be accounted for. What I am trying to calculate is how much force will be required to change the direction of this angular momentum. Any help in this matter would be greatly appreciated.

That is a very interesting problem, and it does not have a nice, neat, clean answer. It depends on how fact you try to move the boom that has the spinning mass, that is, how fact the boom angle changes. This of course depends on how fast the hydraulic cylinder changes length, although not in a nice linear fashion. Good problem!
