Hypothesis

Our stucture was that both tennis ball cans are cut in half and one placed in the other at a 35 degree angle. The height was to send the ball an extra little distance since it would start higher. We had no combustion chamber because we believed that the pressure would go down just getting to the main firing chamber. With this in mind, I predicted that it would go at least 3 feet.

Reflection

Our cannon's design used Boyle's law of pressure and volume being inversely related by lowering the volume by cutting the second tennis ball cannon in half. Thus increasing the pressure, so the ball will go farther. Our cannon didn't fire due to the cold weather. This follows Gay Lussac's law where temperature and pressure are directly related. The cold temperature decreased the pressure and therefore, out cannons didn't fire. We probably have made our cannon more stable if we did it again.

Math

My reasearch led me to think the best angle would be 40 degrees. I cannot find the source again (I've looked all over the place). Since I found that the best angle was 40 degrees, we aimed for 35 degrees. This is for the reason that if we overshot 40 degrees the distnce would halve, but if we undershot 40 degrees it wouldn't change as drastically.

The formula for determining velocity is:
vf = g * t

Discussion

The men in Charge of the Light Brigade displayed courage and honor. They courageously charged to their known death. They might have wanted to die with honor instead of being cowards and disobeying orders. There were leaders in the mix, they were the ones who charged first. Those who needed that extra bit of encouragement were the followers. I didn't see any justice or vengance in this poem.

Overture of 1812

I didn't really understand this poem. But I really got some idea of previous war though. There were soft parts where the is nothing going on and there are parts when shots are going everywhere.

1900's-Present

The T-92 240mm howitzer is like a heavy armour, rolling howitzer. It shot 360 lb projectile 14 miles. Its primary function was to destroy places or help the army. With its heavy armour, it had some protection as well. It is an improved cannon with a farther range and more destructive ammunition. Considering the power of this machine, you could not even see it coming until it hits you. Daily cannons like these give everyone a reason to fear.

1800's-1900's

This is the 12-pounder Napoleon, obviously used by the French. It was composed of bronze and shot shells, shots, canisters, and grapeshot(hurt people because shell exploded). Their primary function was to kill individuals, so they tended to explode to harm more people. They were used in the civil war, so they were rolled around and fired by sticking a flame in the hole in the back-much easier than using counterbalances. They were also used on ships with chain shots to damage masts to strand the enemy ship. These were used along the new guns and was the first major use of gunpowder.

Pre-1700's

This is a counterpoise trebuchet. It is composed of mainly just stone and rope.It fired stones mainly, but could also fire any object that would damage castle walls or incoming enemy troops. I found that an interesting thing they threw was burning sand because it gets trapped inside armour. It required quite a few men to reload, reset, and fire. It required even more men to move it around. It's function was to greatly help lay siege to a castle or protect the castle by launching out of it. Either way it dramatically imacted war as the first form of artillery.
