Final answer:
A nutcracker functions as a second-class lever where the fulcrum is at one end, the effort is applied at the other end, and the load is in the centre.
Step-by-step explanation:
A nutcracker is an example of a second-class lever. In this type of lever, the fulcrum is at one end, the effort is applied at the other end, and the load (the nut) is in the middle. This setup allows a small amount of force or effort to be exerted on the long arm of the lever (where you apply your force) to create a large amount of force on the short arm of the lever (where the nut is) allowing the nut to be cracked.
