Taylor - Looks like a good start, it would be useful to plot the linear density function verus x, for just the shell, and look for consequences to the weight, and weight distribution, fat rings at trasition points, etc. This might also lead you to make a more sophisticated model of the density function accounting for the bat geometry changes. I'll bump up your April 14 assignment score another 5 pts for the effort. Bill Jumper 080418

Taylor - Looking at your May 1 Modeling Tool Update, in particular, looking at the 'Modeling Tool' worksheet, suggest plotting column U (delta Mass element, effectively linear density) versus x. Ultimately the linear density is the final input to your bat model that drives everything. The values on this worksheet look OK, could be smoother, but on the 'Modeling Tool with Better Data" worksheet the linear density values are too large by 2 ro 3, and they are not too smooth. The shape of the linear density function should be a monotonically increasing function from handle to barrel, mirroring more or less the diameter of the bat, and starting from the handle end at 0.4-0.5 oz/inch to 0.6-0.7 oz/in at the barrel end.
