I will try and cut to the chase here. My recent hobby involoves variations of catapults and trebuchets. I am finding a need for some physics in rotional mass type situations. I have no background in math beyond basic arithmatic but I have always been pretty good with math logic in a general sense.
My question is this, I don't have a need for precise answers as much as I do rounded reasonable figures for starting tuning processes and exploring feasability of designs. One method I have been using that I am not too sure of is to find the point on a rotating mass that seems to be the center of mass and then applying all the mass at that point of rotaion and simply calculating the kinetic energy based on the speed at the particular radius point I have figured to be the center. Will this give me reasonably close numbers? Steve
