Hi, how do you select the other two points when plotting the angular displacement graph? I have no problem selecting the center of the golf ball but the other two points are giving me issues. Should I select the edge at the end of the green (where the railing ends at the center), what about for the initial position of the ball? Any help would be greatly appreciated.
Thank you for your amazing tutorial. While watching you tutorial, I found that at 17:23 you also used LinearMotor 4,5,6 and RotaryMotor in your motion analysis. Could you please explain why do you use these motors? What are the roles of these motors?
Linear Motor 4 - pulls the putter head backwards a distance. Linear Motor 5 - drives the putter forward at 5mph. These must be separate because one is a distance application, and one is a velocity. Linear Motor 6 - Stops the shaft from moving forward. Rotary Motor - Stops the shaft from rotating. Once the putter hits the ball and the reactions happen, and the ball moves away, these motors turn on to prevent the putter from sliding or rotating. In reality we would be holding the putter steady, and these are representing that.
@@goengineer So the rotary motor only turns on once the ball is hit, but it looks like the putter is constrained to the midplane (or toe/heel hit planes) throughout the analysis? If I suppress this mate, the putter does not stay straight at the linear motor pulls it back before the shot

I need that printed putter stat!
