how the arms can be used in the pendulum model. can they add more speed then the pivot alone
take a child and put them on a swing set. you are going to swing the child and the child is held in place at 9:00 before you swing the child, they will swing down to 6 and up to 3. While they are going down gravity and torque from the shoulders will propel them. can you assist those two with the arms as well?
3 options,
A. now you could just drop the child, gravity, shoulder turn and add no arm force, they will probably swing just past 3.
B. You cauld have the child drop from 9:00 while you stand by the bottom of the arc and try to apply help from the 7:30 position, the child is going fast by that time and you will be lucky to add 5% to the childs speed, so they will swing up slightly where they swung in option A
option C. You could stand at the top and push them as they dropped and pulled. At this point they are going the slowest and your help, along with gravity and the shoulders can propel them way past 3
throw from the top, the best way to add speed if you know how to do it right?
