The swinging counterweight trebuchet. On internal friction
E Horsdal
Mechanical energy is lost to friction during a shot with a trebuchet. The losses are mainly due to sliding friction at the bearings for the throwing arm and at the hinge for the sw…

The swinging counterweight trebuchet. On internal forces
Erik Horsdal
The forces that act internally in a trebuchet as it delivers a shot depend on the motions of throwing arm, counterweight and sling. These motions are considered known experimentall…

The swinging counterweight trebuchet. Experiments on inner movement and ranges
Erik Horsdal, Filip Drejer Johansen, Jonas Rasmussen
The inner movement of a trebuchet with swinging counterweight was measured inside a laboratory by the use of rotation sensors to determine angular coordinates for beam, counterweig…
