Question

simple machines
cutting tools such as axes, scissor blades, and nail points are all examples of ___.
a. levers
b. inclined planes
c. wedges
d. screws

Explanation:

A wedge is a simple machine that is thick at one end and tapers to a thin or sharp edge at the other end. Axes are used to split wood by driving the wedge - shaped blade into it. Scissor blades cut by applying force with their wedge - like edges, and nail points are designed to pierce materials easily due to their wedge - like shape. Levers involve a rigid bar that pivots around a fulcrum. Inclined planes are flat surfaces at an angle. Screws are cylindrical with a helical ridge.

Answer:

C. wedges
