examples of an inclined plane are the playground slide,
steps, a ski jump, and a wheelchair ramp. An inclined
plane is a flat surface set at an angle (other than
a right angle) against a horizontal surface. An
inclined plane is a simple machine with no moving parts.
It is simply a straight slanted surface.
The inclined plane permits you to overcome a large resistance
by applying a relatively small force through a longer distance
than the load is to be raised. The steeper the slant, the
more work it takes to go up the inclined plane. As the slant
of an inclined plane decreases, the mechanical advantage
increases. It takes less force to raise the object, but
the object must move through a longer distance.
the steps you climb at school or in your home. They help
you move from a lower level to a higher level by cutting
a little space into the incline to make it easier for you
to use. Can you imagine how hard you would have to work
to climb a ramp as steep as your stairway?
designing motion machines you must be aware of gravity at
work with inclined planes. An object rolling down a ramp
will gain speed. Inclined planes can also be used in reverse
to slow things down to a stop. Inclined planes can be used
to raise or lower objects and as a way to gain or lose momentum.
