Question

An ax is used to chop wood. The metal part chops through the wood, pushing it apart into two smaller sections. which simple machine is found on the head of this ax?

Answer 1

The simple machine found on the head of the  ax is Wedge. A wedge is an inclined plane that can be moved. When an ax is used to split wood, the ax handle exerts a force on the blade of the axe, which is the wedge. That force pushes the wedge down into the wood. The wedge in turn exerts an output force splitting the wood in two.
