No, a wedge does not have a fulcrum. A wedge is a simple machine that consists of two inclined planes that meet at a thin edge, allowing it to push objects apart by applying force on one end. It does not pivot around a point like a fulcrum.
inclined plane
The pivot point of a lever is called the fulcrum.
No, a teeter-totter is not a form of a wedge. A teeter-totter is a simple machine that involves a pivot (fulcrum) and a lever, while a wedge is a different type of simple machine typically used to separate or lift objects.
An electric motor is not a simple machine, because it uses electric energy, which is not mechanical energy, which powers simple machines.
A wheelbarrow is a type of lever, specifically a class 2 lever, where the "fulcrum" is at one end, the effort (you pushing down on the handles) is at the other end, and the load (the weight you're carrying) is in the middle. It does not incorporate a wedge or a pulley in its basic design.

They have two levers on a single common fulcrum. The edge of each lever is a wedge.
It's a lever, where the fulcrum is at the same location as the driving force (i.e. your hand on the handle). Thus it is a first class lever, since the force applied is on the other side of the fulcrum from the load.

That would be a wedge as the blade is sharpened to an edge. It could also arguably be a lever, the chopping board being a fulcrum.
A rocking horse typically consists of a lever (the horse's body), a fulcrum (the rockers on the base), and possibly a wedge (for stability). The rocking motion is created by the lever and fulcrum working together.
An electric motor is not a simple machine, because it uses electric energy, which is not mechanical energy, which powers simple machines.
