- Current UV light system designs incorporate the use of un-shielded “hot” cathode lamps that prefer ambient operating conditions around 120 degrees F. The cooling effects of the air stream along with placement near the coil can severely reduce the operating life of these lamps and in some cases damage them.

Homework Help: What is the length of the catapult? A Jet fighter plane is launched from a catapult on an aircraft carrier. It reaches a speed of 42 m/s at the end of the catapult, and this requires 2.0s. Assuming the acceleration is constant, what is the length of the catapult? Am I looking at this correctly? final velocity(Vf) is 42 m/s. initial velocity(Vi) is 0 m/s.

Physics of Catapults The photo is courtesy of: http://members.multimania.nl/onager/ballista.htmlMangonelThe Mangonel is what many people think of when they think of a catapult. From the Latin word manganon meaning engine of war. The Mangonel was invented by the Romans in 400 BC. The Mangonel consists of a long wood arm with a bucket (early models used a sling) with a rope attached to the end. The arm is then pulled back (from natural 90o angle) then energy was stored in the tension of the rope and the arm. Then the bucket would be loaded.

How Aircraft Carriers Work When the U.S. Navy really needs to impress people, it flies them out to one of its super aircraft carriers. Standing 20 stories above the water and stretching 1,092 feet (333 meters) from bow to stern (about as long as the 77-story Chrysler Building is tall), the sheer bulk of these ships is awe-inspiring.

- If that happens, future spacecraft might use a version of a linear induction motor launch system, which essentially is an electromagnetic catapult that would move a spacecraft along a rail system with an air-breathing engine second stage and a rocket-powered third stage completing the job of propelling the vehicle into space, Dryden researcher Kurt Kloesel explained.

Catapult: The Long-Reaching History of a Prominent Medieval Siege Engine It was usually quite difficult for an enemy to capture a castle, and for that, an attacking army needed siege engines. One of the most important and efficient siege engines was the catapult. The Roman Onager . The catapult was a weapon used since ancient times. In its most basic form, the catapult may be described as a “one-armed stone thrower”. In the Roman world, a catapult-like siege engine known as the ‘onager’ (meaning ‘wild ass’) was used when the Romans were besieging an enemy.

Physics of Catapults This made Catapults an essential. Catapults were used to launch missiles (many different objects were utilized). These missiles were either launched directly at the wall to cause maximum damage to the fortifications or were launched over the wall to lay siege on the population within the protective walls.

Evolution of the Aircraft Carrier The U.S. Navy’s first aircraft carrier, USS Langley (CV 1), was converted from the collier USS Jupiter (AC 3) and recommissioned March 20, 1922. Lagley had a displacement of 11,500 tons and measured 542 feet in length. She could travel at a speed of 15.5 knots (17.8 mph) and boasted a crew of 468 personnel.

At what speed is a plane launched off an aircraft carrier? An aircraft is designed to take off into the wind so it is easier to control. When one is catapulted off the deck of the carrier it has all the speed it needs to fly but it gives the pilot only seconds to get the aircraft under control. If it was to be catapulted with the wind not only would the pilot have to struggle with control but with gaining lift.

How does a catapult work? 3. A trebuchet is a weighted beam that swings a sling carrying the projectile (see this page for pictures). ­Both catapults and ballistas work by storing tension either in twisted ropes or in a flexed piece of wood (in the same way an archery bow does, but on a larger scale).

Catapult Physics Catapult Physics – The Mangonel Source: http://en.wikipedia.org/wiki/Catapult. Author: ChrisO The above picture of the mangonel is what people are most familiar with when they think of catapults. The mangonel consists of an arm with a bowl-shaped bucket attached to the end. In this bucket a payload is placed.

How does a catapult work? A trebuchet tends to be easier to build because it consists simply of a pivoting beam and a counterweight that rotates the beam through an arc. Catapults can launch things a fair distance -- 500 to 1,000 feet (150 to 300 meters) is common. It is surprising how much energy they can store. The gears are important, because they create a winch. The winch allows a person to put a great deal of energy into the catapult over a period of time.

Catapult Physics Catapult physics is basically the use of stored energy to hurl a projectile (the payload), without the use of an explosive. The three primary energy storage mechanisms are tension, torsion, and gravity.

- A catapult can be used to make a ball follow different trajectories. In the top picture, the ball follows a high trajectory to go over the castle wall. In the bottom picture, it follows a low trajectory to go into the castle wall. Both of these are bad news for the people inside the castle!

- Definition: The ballista is a type of siege engine and catapault that revolutionized warfare. It was used first in 398 B.C. in the successful siege of Motya, a Phoenician city in western Sicily, by Dionysius I, tyrant of Syracuse.
