A nutcracker primarily consists of two simple machines: the lever and the wedge. The handles of the nutcracker act as levers, amplifying the force applied when squeezing them together. The wedge is represented by the curved or pointed part that cracks the shell of the nut when pressure is applied. Together, these simple machines efficiently crack nuts with minimal effort.
