Floating arm trebuchet – Wikipedia

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. In contrast, a floating arm trebuchet features an axle on the arm freely moving along a horizontal glide track.

Perdue 15 November This page was last edited on 5 Aprilat Five Machines That Floaging the World. Their defining feature is free movement of an axle on the throwing arm, [2] and a linear drop channel for the counterweight. Reducing the drop distance of the wheel axle to the glide track would reduce damage, but also reduce the range of the trebuchet. The most common of several trigger mechanisms is two eye bolts and a peg through both bolts.

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 reset the device, the counterweight must be raised back to the original height and flosting in with the trigger mechanism.

Retrieved from ” https: Views Read Edit View history. 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.

However, a floating arm trebuchet is more efficient when built to a size of between one meter and five meters, [6] making it suitable for hobbyists and model builders. In larger designs, the trigger system is applied at the top of the drop channel. Retrieved November 15, Kids Learn by Making Stuff.

Floating arm trebuchet by Freddy Moreno on Prezi

Retrieved November 13, 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.

The design and construction of such machines is a popular project assignment in post-secondary engineering classes. From Wikipedia, the free encyclopedia. To reduce friction of the sling on the launch track, the track should have a smooth surface.

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. The floating arm trebuchet uses a counterweight held on top of a plas drop channel to transfer potential energy into kinetic energy.

A floating arm trebuchet has three points of contact where friction can interfere with efficiency. A regular trebuchet is a better realistic war machine.

While this is happening, the wheel is moved backwards by the torque acting on the arm from the counterweight. Large scale designs require special trigger mechanisms that can hold the weight of the throwing arm. Upon releasing the trigger, the counterweight is allowed to drop through the channel. The dropping of the counterweight forces the arm to swing to one side of the glide track and quickly jerk rtebuchet the opposite direction to launch a projectile.

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 arm is on a moving axle and the torque acts on the entire structure, preventing stalling.

The Floating Arm Trebuchet is a counterweight siege weapon which is a modern variation [1] of the medieval trebuchet. While the floating arm design can have a lighter frame than a traditional trebuchet because the overall forces produces are less, [5] the arrm of the arm on the glide track will cause eventual damage and may need maintenance.
