Trebuchet Research Paper

A trebuchet is a siege weapon most commonly used in the middle ages. It uses gravity to propel an object. There are competitions held today called "Pumpkin Chunkin '" which use trebuchets to launch pumpkins as far as possible. The common question is what the dimensions should be when making it. Should the arm be longer or shorter? Should the counterweight be heavier or lighter? These questions have been asked by competitors in trebuchet competition as well as engineers. And this is why the project is in the field of mechanical engineering.

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

“The missile carries a warhead weighing 1,870 pounds. It has three different fuses to insure detonation.” It is easy for society to overlook the crushing

No steel-beam high-rise had ever before (or since) completely collapsed due to fires! However, such complete and nearly symmetrical collapses in tall steel-frame buildings have occurred many times before—all of them due to pre-positioned explosives in a procedure called “implosion” or controlled demolition.

A Trebuchet is a weapon used during the medieval ages in siege warfare. The trebuchet was used for the defense of towns, strongholds, and cities. First the materials used to build medieval trebuchets. Second the origins of trebuchets. Third how trebuchets were transported.

5. “Suddenly the tank exploded with a noise like the sound of a thousand machine guns,” said to the newspaper.

The shell was ejected out the barrel of the weapon, spinning in midair. Lead sliced through the sky, darting towards its target. A faint white tracer followed along the bullet. Quickly, the bullet hit the green and blue barrels. A spark erupted, which soon turned into a blazing flower of fire. It rose into the sky like an angry god, yelling its thunderous roar. A silent killer, the shockwave, swiped out of truck and into the surrounding vicinity. Guards flew backwards onto the asphalt, screaming all the way.

After hitting 2 of the windows with a hammer he started firing over the crowd at the music festival, by the end he ended up firing hundreds of rounds at a distance of about 450 meters. Many

The FEMA document focuses on numerous different ways to minimize damage by car bombs to buildings. The publication focuses on site design for buildings at high risk of car bombs, because they have the capacity for maximum damage and casualties. There are design alternatives, such as re-alignment of the approach to buildings that slows down vehicles and providing adequate stand-off distance between bomb vehicles and the buildings to reduce impact. Car Bombs require a different set of mitigation measures that often require modifications to buildings.

During its final testing, however, the Panjandrum nearly killed a filmer of the event, roaring towards him and shooting rockets in every direction. Due to safety reasons, the

When we think of catapults we usually imagine them firing at castle walls during the medieval times, or standing in the background of a large army clashing with another in an action movie. However, catapults have a long and intricate history that twists and binds with our own, dating all the way back to 399 B.C. First documented by the Greek historian, Diodorus Siculus, in the form of an early design for the Ballista (type of catapult). Catapults were a staple for siege warfare all throughout history. The catapult was used by many different cultures, notably the Greeks, Roman, and Chinese in siege warfare; also

* The relevance of this experiment is similar to understanding a real airplane. Paper airplane models are derived from an actual plane these days. The design of an airplane has so much to do with distance, hang time, speed, and many other factors. Understanding the models I have chosen to make help me

Purpose: The purpose of this Physics Lab is to investigate what factors determine the amount of flexion of the cantilever. Hence, the objective is to establish a relationship between the length of a cantilever, which may give some insight into the physics of cantilevers.
