You have a pizza slicer and youre using it to cut pizza. Describe the Force Diagram.
Treat the slicer as a rigid body and explain the forces acting on it while the wheel rolls through the pizza. Identify the applied hand force, contact forces, friction, cutting resistance, and any resulting torque. State your assumptions and explain how the diagram changes if the wheel rolls freely versus slides.
