A floating arm trebuchet has three points of contact where friction can interfere with efficiency. Retrieved November 15, The arm is on a moving axle and the torque acts on the entire structure, preventing stalling.
Retrieved from ” https: Perdue 15 November 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. xrm
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. Large scale designs require special trigger mechanisms terbuchet can hold the weight of the throwing arm.

The design and construction of such machines is a popular project assignment in post-secondary engineering classes.
Trbuchet 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 eventual damage and may need maintenance.
Kids Learn by Making Stuff. Reducing the drop distance of the wheel axle to the glide track 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. The dropping of the counterweight forces the arm to swing to one side of the glide track and quickly jerk plajs the opposite direction floatinh launch a projectile.
A regular trebuchet is a better realistic war machine.

Retrieved November 13, The most common of several trigger mechanisms is two eye bolts and a peg through both bolts. From Wikipedia, the free encyclopedia. The f,oating 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,  making it suitable for hobbyists and model builders. 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.
To reset the device, the counterweight must be raised back to the original height and locked in with the trigger mechanism. A traditional trebuchet, which is simple to engineer, consists of an arm resting off-centre on an axle with plabs hinged counterweight at the short end of the arm.
While this is happening, the wheel is moved backwards by the torque acting on the arm from the counterweight. Upon releasing the trigger, the counterweight is allowed to drop through the channel. In larger designs, the trigger system is applied at the top of the drop channel.
In contrast, a floating arm trebuchet features an axle on the arm freely moving along a horizontal glide track. Views Read Edit View history. 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.
