Becase your teeth split food in half like a wedge.
A saw is considered a wedge because its teeth create a narrow splitting edge that helps separate materials when the saw is moved back and forth. This cutting action is facilitated by the shape of the teeth that help wedge into the material being cut.
If you think about this, you can figure it out. What shape is a shark's tooth? It's a triangle, right? What machine is a triangle shape? The only simple machine that looks like a triangle is a wedge.
The mechanical advantage of a wedge in this case would be 1, as the input force is equal to the work done. This means that the wedge is not providing any mechanical advantage, as the force required is equal to the work accomplished.

a WEDGE!
A saw is considered a wedge because its teeth create a narrow splitting edge that helps separate materials when the saw is moved back and forth. This cutting action is facilitated by the shape of the teeth that help wedge into the material being cut.
Teeth form an angle which is pressed into food. The pressure forces the food to separate to either side of the angle and the food is split over and over again at different angles.
If you think about this, you can figure it out. What shape is a shark's tooth? It's a triangle, right? What machine is a triangle shape? The only simple machine that looks like a triangle is a wedge.
they split food in half, like metal wedges do to wood.
Chopping wood (an axe), a doorstop and even you teeth!
The body part shaped like a wedge is your incisors ( the kind that look like shrake teeth) !
