Range Equation

This is the range equation that we used for our cannons. V = initial velocity, θ = launch angle in degrees, R = distance of the launch, and G is about 32.2 feet/second.

Since our cannon had no range, our initial velocity is 0.

However, θ is equal to 38º.

1912: "Vickers Machine Gun"

The Vickers machine gun was created in Kent and introduced in Britain in 1912. It was essentially an improved version of a Maxim machine gun. It was, mainly in World War II, until 1968. It uses a 250 round fabric-belt magazine and used water as a self-cooling mechanism, weighing about 50 pounds.

Before 1700: "The Stirling Warwolf"

The "Stirling Warwolf" was invented in 1304 by Edward Longshanks. It was made for the English army and it was extremely effective. With one shot, it could destroy a section of a castle wall. It successfully ended the siege of Stirling Castle.

1863: "The Swamp Angel"

"The Swamp Angel" was an 8-inch, 200-pound Parrott siege fun, created by Major General Quincy Gillmore in 1863. It was used in Charleston, South Carolina, as a threat to General Beauregard to evacuate Morris ISland and Fort Sumpter. If he failed to comply, they would begin firing at the city. General Beauregard did not believe that the threat was valid and refused to leave. General Gillmore unleashed fire, causing mayhem and chaos throughout the city.
