A lever
The two main parts of a psychrometer are a rain gauge and a mesauring stick
An example of potential energy: a cocked trebuchet
I'm unsure as to what exactly a distance magnifier is so hopefully someone with expertise in trebuchets can add to this. However I am confident that a trebuchet works on the principle of a lever. A lever is a force magnifier. Yet a trebuchet also uses a sling to launch the projectile in a parabolic arc which has the effect of increasing the distance, so perhaps it qualifies as both? A lever is most often used as a force multiplier, where the load moves through a smaller distance than the applied force, but in the case of a trebuchet the lever is used in the opposite sense. The load moves through a greater distance than the applied force and so the trebuchet is a distance multiplier.
load force divided by effort force
The five basic parts of a trebuchet are the frame, couterweight, beam, sling and guide chute.
Trebuchet MS was created in 1996.
Trebuchet is catapult that uses weight to fire.
LIFE LIFE
the purpose of a trebuchet is that it can throw heavy things in war
the trebuchet was believed to have started in china around 300 bc
The trebuchet was much like a catapult. It was replaced with the cannon, and later, firearms.
The Trebuchet first appeared in china in about the 4th century BC
As far as i know there are three: the basic catapult, trebuchet, and the floating arm trebuchet.
A trebuchet is defined as a machine used in medieval siege warfare for hurling large stones or other missiles. The first trebuchet was invented by the Chinese in the 4th century BC.
