How can a trebuchet use gravity

One of the questions we get asked frequently is why use capacitance? Resistive sensors have been used for a long time…so why change? Here is an attempt to answer this question: What is capacitance It is the ability of a system to store charge.

Click here for Battle Ready Medieval Swords and Armors Longswords The Longsword is a type of European sword used during the late medieval period, approximately to with early and late use reaching into the 13th and 17th centuries, respectively.

Learning From Lab. A common Physics lab involves the analysis of a pendulum in its back and forth motion. The transformation and conservation of mechanical energy is the focus of the lab. A kg ( gram) pendulum is typically released from rest at location A. Arming Swords. The arming sword (also sometimes called a knight's or knightly sword) is the single handed cruciform sword of the High Middle Ages, in common use between ca. and , remaining in rare use into the 16th century. The trebuchet is a compound machine that makes use of the mechanical advantage of a lever to throw a projectile. They are typically large constructions (up to 30 meters [ feet] in height or more) made primarily of wood, usually reinforced with metal, leather, rope, and other materials.

Longswords have long cruciform hilts with grips over 10 to 15in length providing room for two hands. Straight double-edged blades are often over 1 m to 1. The longsword is commonly held in combat with both hands, though some may be used single-handed.

Longswords are used for hewing, slicing, and stabbing. The specific offensive purpose of an individual longsword is derived from its physical shape. All parts of the sword are used for offensive purposes, including the pommel and crossguard.

English Medieval and Renaissance manuscripts refer to the longsword as the two hand sword. The terms "hand-and-a-half sword", "greatsword", and "bastard sword" are used colloquially to refer to longswords in general.

The longsword, with its longer grip and blade, appears to have become popular during the 14th century and remained in common use, as shown through period art and tale, from to The longsword was a powerful and versatile weapon. For close personal infantry combat, however, the longsword was prized for its versatility and killing capability.

Hand and a half swords were so called because they could be either a one or two handed sword. While nearly every longsword is in some way different from one another, most contain a few essential parts.

The blade of the sword forms the cutting portion of the weapon and is usually double-edged.

Blades came in a variety of shapes and sizes. Broad and thin blades are more effective for cutting-oriented longswords while thick tapering blades are found on varieties more effective at thrusting.

However, all longswords were effective at cutting, slicing and thrusting and variations in form made only minor alterations in use. The hilt comprises the portion of the sword that is not the blade.

Like the blade, hilts evolved and changed over time in response to fashion and as the swords were designed for different specific purposes.

The blade of the medieval longsword is straight and predominantly double edged. The construction of the blade is relatively thin, with strength provided by careful blade geometry. Over time, the blades of longswords become slightly longer, thicker in cross-section, less wide, and considerably more pointed.

This design change is largely attributed to the use of plate armour as an effective defence, more or less nullifying the ability of a sword cut to break through the armour system.

Instead of cutting, long swords were then used more to thrust against opponents in plate armour, requiring a more acute point and a more rigid blade. However, the cutting capability of the longsword was never entirely removed, as in some later rapiers, but was supplanted in importance by thrusting capability.

Blades differ considerably in cross-section, as well as in length and width. The two most basic forms of blade cross-section are the lenticular and diamond.

Lenticular blades are shaped like thin doubly convex lenses, providing adequate thickness for strength in the centre of the weapon while maintaining a thin enough edge geometry to allow a proper cutting edge to be ground.In addition to building prototypes of a trebuchet, you can also use physics calculations or even a computer simulation to help you design it to have the best range.

History and Details on Trebuchets. The Commander's Trebuchet in Action. Updated July 29, The Trebuchet did not exist to be used by the Roman Legions, although the Onager catapult developed by the Romans, equipped with a sling, foreshadowed the mechanics and action of the Trebuchet of the Middle Ages.

The exact beginning of trebuchets is not known but we do know that they first started appearing around the 12th century.

There were similar siege engines that date back as far as the 6th century but these were human powered rather than gravity powered with counterweights.

A mangonel, also called the traction trebuchet, was a type of catapult or siege engine used in China starting from the Warring States period, and later across Eurasia in the 6th century AD.

Unlike the earlier torsion engines and later counterweight trebuchet, the mangonel operated on manpower pulling cords attached to a lever and sling to launch projectiles.

Building and testing the trebuchet with a lever and weight system was a good way to witness science “at work. ” This system uses gravity to activate propulsion.

The force of gravity applied to the counter-weight of the trebuchet creates the action that moves the projectile through the air as the trials show.
