What type of lever does a pizza cutter have?

The handle is at an angle. Type B. If you sketch it, the connection point for the rotating knife (a wedge) is behind the contact point. Look at one closely with the handle at an angle.

Which are the two simple machines present in a pizza cutter

A pizza cutter typically uses a Class 1 lever.

To determine the type of lever that a pizza cutter has, we should first understand the three types of levers:

1. First-Class Lever: In a first-class lever, the fulcrum is located between the effort and the load. Think of a seesaw, where the pivot point is in the middle, and there is an effort on one end and a load on the other.

2. Second-Class Lever: In a second-class lever, the load is located between the fulcrum and the effort. A classic example is a wheelbarrow, where the load (for example, a sack of potatoes) is placed in the front-wheel container and the effort (when you lift the handles) takes place at the opposite end.

3. Third-Class Lever: In a third-class lever, the effort is applied between the fulcrum and the load. A common example is a pair of tongs, where the effort is exerted by your hand, the fulcrum is the joint of the tongs, and the load is the object you're picking up.

Now, let's consider a pizza cutter. A pizza cutter typically consists of a wheel-shaped blade and a handle. The fulcrum is located at the point where the blade and handle meet.

In a pizza cutter, as you roll the blade over the pizza, the force or effort is applied at the handle, and the load is the resistance of the pizza crust that you're cutting.

Since the fulcrum is positioned at one end (the handle) and the effort is applied at the same end, while the load is at the opposite end (the blade), a pizza cutter can be categorized as a class-three lever.
