Counterweight

The trebuchet was used to hurl large stones at castles in the medieval era. The trebuchet was a new war machine that terrorized castles throughout the British isles. With it’s origin dating back to China in 300 B.C., the trebuchet was used primarily by the French until the twelfth century. During the Siege of Dover, the French attacked the British stronghold at Dover. Once King Edward the first of Britain laid his eyes on this weapon he knew he must construct one for Britain. He told his master…

engineering. The primary components included a wooden frame, typically made from oak or other hardwoods, and a counterweight system. The throwing arm, or "beam," was often constructed from lighter woods to ensure flexibility and reduce stress during launching. The sling, a critical element for delivering projectiles, is crafted from durable materials such as leather or woven fibers. The counterweight, usually composed of stones or sandbags, provides the necessary force to propel the projectile.…

When the trebuchet is fired, the weight box falls and the force of gravity causes rotational acceleration of the attached throwing arm around the axle (the fulcrum of the lever). The throwing arm is usually four to six times the length of the counterweight portion. These factors multiply the acceleration transmitted to the throwing portion of the arm and its attached sling. The trebuchet derives from the ancient sling. It originated in China. A variation of the sling, called staff sling,…

carried in pieces on the back of their work-animals, but most were built in place. This required having the right tools and materials. Also, the workers had to be smart. It was also expensive to build. Another disadvantage was that often the counterweight portion of the trebuchet was misjudged against the weight of the projectile. When the trebuchet was set it would misfire, sending the projectile in an unpredictable direction hitting things that was unintended or killing innocent people…

most the measurement could be off is one gram. I tied a string to the cart and placed it over the wheel and attached the string to the counterweight, which included a weight hanger and weights. I then determined the hanging mass required to make cart move at constant velocity to determine the friction force on the system. I added paper clips to the counterweight and then pushed the cart towards the pulley, during which the photogate measured the speed. I continued to add paper clips until the…

Catapults can be used in many ways. They were used in ancient history times. There are many types of catapults. When launching a projectile, physics is used in the catapult.

Medieval Weaponry Information Report What are the types of Maces that were used? The types of Maces and Clubs are, Morningstars, holy water sprinklers, flails, war hammers and the horseman pick. What is a Polearm? What are the types of Polearms? A polearm is a close combat weapon. The fighting part of the weapon is usually on the end of a long wooden pole, this made it hard for the enemy attackers to grab and pull away the weapon. The Polearm could also deal a lot of damage if it landed a…

There has never been a lot of research on american motocross and its history. The sport has been around for a while now and is finally gaining a name for itself. The sport started naturally with a group of just average people riding their motorcycles on a course they designed with maybe a few man made jumps. Motocross really took a step in the direction it is in today when Edison Dye came into the motocross picture. He ran motorcycle touring business in Europe and his travels across the pond…
