Answer:
1.Simple machines that are widely used include the wheel and axle, pulley, inclined plane, screw, wedge, and lever.
2.While simple machines take many shapes, they come in six basic types: Wedge: A device that forces things apart. Wheel and axle: Used to reduce friction. Lever: Moves around a pivot point to increase or decrease
a.lever: machine consisting of a beam or rigid rod pivoted at a fixed hinge or fulcrum.
b.inclined plane: An inclined plane, also known as a ramp, is a flat supporting surface
c.wheel and axle: The wheel and axle is a machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.
d.pulley: A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction
e.wedge: a piece of a substance (such as wood or iron) that tapers to a thin edge and is used for splitting wood and rocks,
f.screw: A screw and a bolt are similar types of fasteners typically made of metal, and characterized by a helical ridge, known as a male thread.
therefore i conclude that water and oil will never be as one even if you stir them all day.
