Kids Learn by Making Stuff. The Floating Arm Trebuchet is a counterweight siege weapon which is a modern variation [1] of the medieval trebuchet.

Floating arm trebuchet – Wikipedia

Reducing the drop distance of the wheel axle to the glide track would reduce damage, but also reduce the range of the trebuchet. This linear drop of the counterweight is more efficient in transferring potential energy to kinetic energy than the pendulum counterweight motion of a traditional trebuchet.

Technology on Your Time. Their trebucheg feature is free movement of an axle on the throwing arm, [2] and a linear drop channel for the counterweight.

Friction when the counterweight is dropping down to the glide strike can be reduced by using silicone grease or a thin film of plastic on the drop channel.

To reduce friction of the sling on the launch track, the track should have a smooth surface.

However, a floating arm trebuchet is more efficient when built to a size of trebucuet one meter and five meters, [6] making it suitable for hobbyists and model builders.

The floating arm trebuchet loses the range advantage over regular trebuchet at very large scales, because the difficulty in construction of the drop channel and axle increases with size. The sling or pouch, which contributes to acceleration of the projectile and then releases it at the desired launch angle, is often made using polyester rope or other durable thin material.

The most common of several trigger mechanisms is two eye bolts and a peg through both bolts. The pans arm trebuchet uses a counterweight held on top of a tall drop channel to transfer potential energy into kinetic energy.

The arm is on a moving axle and the torque acts on the entire structure, preventing stalling. Large scale designs require special trigger mechanisms that can hold the weight of the throwing arm. While this is happening, the wheel adm moved backwards by the torque acting on the floatong from the counterweight. In contrast, a floating arm trebuchet features an axle on the arm freely moving along a horizontal glide track. While the floating arm design can have a lighter frame than a traditional trebuchet because the overall forces produces are less, [5] the impact of the arm on the glide track will cause eventual damage and may need maintenance.

The dropping of the counterweight forces the arm to swing to one side of the floatlng track and quickly jerk in the opposite direction to launch a projectile. Retrieved from ” https: A traditional trebuchet, which is simple to engineer, consists of an arm resting off-centre on an axle with a hinged counterweight at the short end of the arm.

Retrieved November 13, In larger designs, the trigger system is applied at the top of the drop channel. The design and construction of such machines is a popular project assignment in post-secondary engineering classes.

This page was last edited on 5 Aprilat Retrieved November 15, To reset the device, the counterweight must be raised back to the original height and locked in with the trigger mechanism. Perdue 15 November From Wikipedia, the free encyclopedia. The release mechanism is a hook with a specific bend in its tip to determine when centripetal force will release one end of the sling, freeing the projectile to continue on its path.

A regular trebuchet is a better realistic war machine. Upon releasing the trigger, the counterweight is allowed to drop through the channel. Five Machines That Changed the World. A floating arm trebuchet has three trebucher of contact where friction can interfere with efficiency.
