Simple machines that are used in Weapons

[Antuntun]

Do you know any weapons that use simple machines?

 

[ISamson]

Catapult uses a first class lever as a force multiplier.

 

[Antuntun]

There are third class catapults as well like the mangonel catapult

I would think axes and other blades could be thought of as a wedge.

When you swing a sword, you are using a lever as a speed multiplier.

I like to consider a rock (or a ram) as a simple machine -- propel it with a small force through a large distance and have it strike something with a large force through a small distance.

Slingshot - stored energy conversion to kinetic ( bow and arrow too )
Pendulum - like when a tree trunk is suspended by vines ( ropes ) and as one walks by triggering the release for the truck to come swinging down.

A lot of simple machines in the torture chamber of yore to cause pain, suffering and confession. would that be a class of weapon? ie non-defensive.
