Cannon


When we started our working on our cannon we first balanced the chemical equation which is C2H5OH + 3 O2 => 2 CO2 + 3 H2O and then we thought of a design for our cannon. We each began looking up different cannon designs and angles that we could have the cannon at. The angle we chose had to be almost perfect; if the ball went to high it wouldn’t gain hardly any distance but if the ball went to low it would have a chance of hitting the ground before its max distance. We came to the decision that cannon should be around 40 degrees so we can maximize its distance. We had to think about our design that we came up with an see if it can hold a angle around 40 degrees. We had to make some improvements to our design to hold our angle. We decide to cut a groove into one of the tennis ball container and stick the other one into it. After building I had some doubts about it but I finally came around to it that this can work.
Materials
1. 2 tennis balls containers
2. scissors
3. Tape

Our teacher to us about the project.


Here we are thinking about how we should design our cannon.

My argument on the ethics of weapon development 


Weapon development is good and bad because of certain reasons that I will be explain through this paragraph. The good things about weapon development are that we can protect our citizens from foreign threats. Another good reason for weapon development is that it improves our defense if anybody tries to attack the United States. The terrible reasons for weapon development are that there is somebody always trying use for evil or for themselves to hurt others. Sometimes after making new weapons some corrupt people sell it to other countries or to other people that puts us in harm’s way. These are my thoughts on weapon development and why won’t you leave comment on my blog stating your thought on it so we can have friendly discussion.  
Cannon Blog: Math Component
Initial velocity equation: (speed (ft/sec))cos(launch angle)
Use the quadratic model h = -16t2+v0t+h0 to solve the following problem.
Blog about the steps you took to solve these problems.

A cannonball is shot upward from the upper deck of a fort with an initial velocity of 192 feet per second.  The deck is 32 feet above the ground. 

Quadratic Model:  -16t2+(192)t+(32)
1.     How high does the cannonball go? __  _602ft_______ (Remember you are looking for a specific part of the vertex.)
2.     How long is the cannonball in the air? _ 12 sec__________ (Remember you can use the quadratic formula.)
1300-Older Cannons


Hand Cannon
The Hand Cannon has a simply design but it is very effective. Although surviving examples are all completely constructed of metal, evidence suggests that many were attached to some kind of stock, usually wooden. Other examples show a simple metal extension from the barrel acting as the handle.


Falconet Cannon
Was a light cannon developed in the late 15th century. The Falconet uses up to 0.5 pounds of black gun powder to fire 1 pound round shot up to 5,000ft. Could also be used to fire grape shots. The Falconet resembles a matchlock musket with two wheels for better mobility. The Falconet was also heavily used during the American Revolutionary War.  

1800-1900 Cannons

12-pounder bronze gun, Model of 1857
It is also known as the Napoleon. This bronze smoothbore cannon can fire 12 pound ball and was considered as a light gun, but it actually weighs 1,200 pounds. A powerful cannon like this can fire explosive shells and can shot up to mile with accuracy. The Napoleon was a favorite amongst some Northern artillerists because of its firepower and reliability


Iron cannon
The iron cannon fire a elongated shell that is only designed for it. It was designed before the war by Captain Robert Parker Parrott; this gun is longer than the Napoleon and has a sleeker design. The Parrott went through several improvement during the war to a larger 3 inch bore and matching the Parrott shell. Parrott Rifles were manufactured by the West Point Arsenal in Cold Spring, New York.

History

Modern Cannons

The M65 Atomic Cannon is the largest artillery gun in the army. It is capable of firing conventional and atomic warheads. The 47m ton gun (aka Atomic Annie) is transported b y two factors. The driver can communicate with other members with a telephone system. It is highly mobile weapon that can adapted to many road condition.
















The mission of the M1A2 Abrams tank is to close with and destroy enemy forces using firepower, maneuver, and shock effect. The M1A2 is being fielded to armor battalions and cavalry squadrons of the heavy force. In lieu of new production, the Army is upgrading approximately 1,000 older M1 tanks to the M1A2 configuration. this cannon can fire many types of shells like M829A2 and Heat rounds.
