Demarini Vendetta Bat

[dash_riprock]

I was being tongue-in-cheek Mark. As an aerobatic pilot I have come to know a little bit about drag and laminar airflow. It seems to me that the drag on the (relatively) slow-moving bat handle would be very small, as would be the corresponding benefit of laminar flow over that 6-8" span. So I believe it is more of a sales gimmick than a revolution in bat technology. But you obviously know more about the fluid dynamics than I do, so maybe you could calculate an estimated increase in bat speed. I'd be interested in your findings.

The act of a bat striking a bat is an example of a collision; actually it is an example of an elastic collision. A collision occurs when a relatively large force acts on colliding particles for a relatively short time. The basic idea of a collision is that the motion of at least one of the colliding particles changes rather abruptly and there is a relatively clean seperation of times that are "before the collision" and those that are "after the collision," in other words an elastic collision.

A force that acts for a period of time that is short compared to the time of observation of the system is called an impulsive force. Momentum is mass X velocity. When momentum is integrated with respect to time over a very very small amount of time one get impulse.

Both the kinetic energy and momentum of the system is conserved and since this is an elastic collision, without going through the deriviation of the equation: The sum of the initial and final velocities of the bat equals the sum of the intitial and final velocities of the ball. Assuming that the collision is an elastic one-dimentional collision the final velocity of the ball equals the sum of the initial and final velocities of the bat minus the initial velocity of the ball.

We know that baseball is a game of inches (or cm, ; I prefer the metric system) and it only takes a small increase the final velocity of the ball to mean the difference between an infielder making an each catch to start a double plan the the batted ball being out of the reach of the infielder.

Look how elastic this ball is compared to a wood bat on this swing by Paul Konerko:

Legalization of this metal bat may legalize older "ax handles" which have not been a traditional part of the baseball handle mix. I have yet to see a wooden bat model adopt an ax handle design. There are many types of ax handles on the market. These handles are designed to ergonomically fit within the hand and provide much better performance in cold weather. Do current rules allow an ax handle design to be used prior to any required "legal approval" in winter baseball meetings?

Nice catch Dash!! but i'm thinkin' media tank?

Could be. Or maybe it's not a game - home run derby or something like that. In any event, get her out of there.

Just kidding - she can stay.
