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. 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.
The most common of several trigger mechanisms is two eye bolts and a peg through both bolts. However, a floating arm trebuchet is more efficient when built to a size of between one meter and five meters,  making it suitable for hobbyists and model builders.

To reduce friction of the sling on the launch track, the track should have a smooth surface. Large scale designs require special trigger mechanisms that can hold the weight of the throwing arm.
In contrast, a floating arm trebuchet features an axle on the arm freely moving along a horizontal glide track. In larger designs, the trigger system is applied at the top of the am channel.
Retrieved November 15, 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.
Retrieved from ” https: While the floating arm design can have a lighter frame than a traditional trebuchet because the overall forces produces are less,  the impact of the arm on the glide track will cause plzns damage and may need maintenance.
While this is happening, the wheel is moved backwards by the torque acting on the arm from the trebkchet.

The arm is on a moving axle and the torque acts on the entire structure, preventing stalling. The design and construction of such machines is a popular project assignment in post-secondary engineering classes.
The trebuchef arm trebuchet uses a counterweight held on top of a tall drop channel to transfer potential energy into kinetic energy. To reset the device, the counterweight must be raised back to the original height and locked in with the trigger mechanism. This page was last edited on 5 Aprilat 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.
Floating arm trebuchet
A floating arm trebuchet has three points of contact where friction can interfere with efficiency. The Floating Arm Trebuchet is a counterweight siege weapon which is a modern variation  of the medieval trebuchet.
Technology on Your Time.
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. From Wikipedia, the free encyclopedia.
Upon releasing the trigger, the counterweight is allowed to drop through the channel. A regular trebuchet is a better realistic war machine. Retrieved November 13, Five Machines That Changed the World. Reducing the drop distance of the wheel axle to the glide trebucchet would reduce damage, but also reduce the range of the trebuchet.
Their defining feature is free movement of an axle on the throwing arm,  and a linear drop channel for the counterweight.
