What are the theoretical mechanical advantages of the 3 different types of levers?
It depends on the output force and input force and what the levers look like. For example: if you can use a type one lever to lift 500 N with 100N, the adv would be 5. But, if you can only lift the 500N with 250N, then the adv is 2.

Why are levers useful?
A lever is a simple machine that changes the distance the force is applied over. It is helpful by since the force is applied over distance you can lift things. One example of this machine is a seesaw and a boat paddle. If we did not have this machine on a seesaw we would stay balance. Levers are devices that increase the force you use them with. Each lever has three main parts: the fulcrum, resistance arm, and effort arm.
