it affects how far the rocket will fly
the ratio of the mean diameter of the body of a rocket or missile to its length
The body tube of a rocket is there for friction. As the rocket comes back down the body tube along with the fins are there to slow it down. Also the longer the body tube the faster your rocket will go. The body tube gives it a narrow edge.
Rubbing a straw against your body transfers electrons from your body to the straw, giving the straw a net negative charge due to an excess of electrons. This charge imbalance can cause the straw to attract lightweight objects like small pieces of paper or dust.
A rocket body tube is the center of a rocket; also the piece that holds the rocket together.
to hold the hole of the rocket
The outer shell of a rocket is called the rocket's body or fuselage. It is designed to protect the rocket's internal components and payload from the harsh environment of space.
turns you into a rocket
The structural system is the body of a rocket, this includes all the parts of the rocket.
It's simply called the rocket body.
It depends on what type of rocket you are building.
Model rockets launch by sliding up a rod/wire that is pointing toward the sky. A launch lug is a small tube (like a drinking straw on a small rocket) glued to the side of the rocket body. You slide the small tube (launch lug) down on the rod. The launch lug and rod guide the rocket to start it in the correct direction until it gets going fast enough that the fins can stabilize it. Visit the links below. The first picture shows a rocket on the rod. It's a little hard to see but the rod goes through the launch lug. At the very beginning of the second link, they are sliding a large rocket lugs onto the rod.
The body of a rocket needs to be long because it helps with the propulsion of the object. It is strictly to help with aerodynamics.
