SUMMARY

The discussion focuses on calculating the force required to change the direction of angular momentum generated by a spinning mass in a project involving a hydraulic cylinder. The relationship between the speed of the hydraulic cylinder's length change and the angle of the boom is crucial, as it influences the force needed. The problem lacks a straightforward solution due to the non-linear dynamics involved in the system. Understanding these dynamics is essential for accurately determining the required force.

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!
