what type of simple machine is a catapult?( incline plane , lever , pulley , screw , wedge, or a wheel and axle) How do you know ?

Respuesta :

The simple machine in a catapult is a lever, although there can alos be a pulley included. Because the load and effort are on opposite sides of the fulcrum, they move in opposite directions. This is why catapults can launch objects.

Answer: Lever

Explanation:

A catapult as a machine is a lever (1st class) because the fulcrum is between the Effort applied and the load(object) to be launched. A first class lever machine is a machine that has the fulcrum in between the effort and the load which makes a catapult a first class lever.

The handle of the catapult is where the effort is applied, the fulcrum is the point of contact between the rubber tied to the stick and the stick itself and the load is the object to be launched.
