Yes -10 is aloud in MSB
Wooden
Hit the ball on the trade mark
Studies have shown that the speed the ball travels after being hit by a metal bat is 3 to 8 miles per hour faster than a wood bat. This would translate to a ball hit for a home run travelling 20 to 50 feet further off a metal bat as opposed to a wood bat. Click on the 'Metal Bat vs Wood Bat' link on this page to read a very interesting article about these studies that were performed on the two different types of bats.
Mo but you have to use a -3 bat in highschool
We live in Northern Delaware and the middle school teams, including parochial and private schools follow the rules for High School. These rule allow a drop of -3 on any non-wooden bat. So my answer is to check with your middle school and see what rules they follow.
AnswerAluminum definitely. Compared to wood, metal is able to more easily compress then regain it's shape. This trampoline effect is what causes the ball to come off the bat more quickly.
Metal bats are hollow and have thin walls that produce a trampoline effect that propels the ball off the bat. Imagine dropping a ball on a trampoline. That rebound effect is what occurs at impact and it helps accelerate the ball with greater velocity than you would get with a wood bat. The sweet spot is also much larger on a metal bat.
A metal bat hits the ball further than a wooden bat because metal is harder than wood.
Vibration in baseball bats comes from hitting the ball outside the sweet spot. Hitting the ball on the tip or handle will sting. Aluminum probably stings worse than wood but it depends on the bat, a solid aluminum will be worse than wood, but a hollow aluminum bat will be better than wood. There are many 2 piece bats on the market like the connexion by easton that are designed to prevent sting
It depends in what school but usually yes
it depends on how hard the ball is it if you hit hard with both meta and wood wood goes farther
Thick wood like a baseball bat is not very flexible so when the ball hits the bat and it bends farther than it can the bat will snap
