My name is Mike. I am a big baseball fan (Go
Washington Nationals!) so thank you for your great
question "How much harder an aluminum bat would
hit a ball compared to a wooden bat?"
Aluminum bats allow baseball player to hit the
ball farther and faster than with a wooden bat for
a few different reasons. The first reason is that
a player can swing an aluminum bat about 5 to 10
miles per hour faster than a wooden bat.
The reason for this that the "balance point"
of an aluminum bat is closer to the handle than
for a wooden bat. The closer the balance point of
a bat is to the handle, the faster a player can
swing the bat. Since the player can swing the
aluminum bat faster, the ball will travel farther
when the player hits with an aluminum bat.
The second reason is that when an aluminum bat
hits a ball, the aluminum bat will very quickly
bend and compress in response to the hard ball,
and then very quickly the bat will spring back to
its original shape. This compress-and-spring
motion causes the ball to shoot off the bat faster
and travel farther than if it is hit with a wood
bat. The motion is similar to jumping on a
trampoline: when you land on a trampoline, the
bottom of the trampoline bends against your
weight, and then springs you quickly back high
into the air. Wooden bats are too hard and dense
to have this "trampoline motion."
And lastly, aluminum bats have a larger "sweet
spot" than wooden bats do. The sweet spot is the
area of the bat that causes the ball to travel the
fastest and farthest. Since aluminum bats have
this larger sweet spot, it is easier to hit balls
that go farther and faster than it is with a
wooden bat. And finally, I have attached a website
that further explains a lot of what I have said.
Hope this answers your question!
