A path on a slope is an inclined plane making it easier to get the recycling bins out to the curb each week for Energy Fred. The trash container also has a wheel-and-axle to make the job easier.
One morning, Tuesday, September 10, 2015, at the intersection of Crater Lake Ave and Everglades I saw that the big boys get the best remote control vehicles! A PG&E contractor is using this underground drilling machine to lay 4″ (?) pipe for power and maybe even fiber optics. Using this machine, they won’t have to dig trenches.
Does this man have the best remote control toy of all and get paid to use it? He remotely controls it down the inclined plane to get it to the street from its trailer.
Stairs are an inclined plane.

The Inclined Plane
An inclined plane is a simple machine with no moving parts. It is simply an even sloping surface. It makes it easier for us to move objects to higher or lower surfaces, than if we lifted the objects directly upwards. It is believed that ancient Egyptians used inclined planes to carry heavy stones to build pyramids.
The resistance force Fr =mg, the weight of the object. It takes work mgh to overcome that resistance force and lift the object to height h. By doing work on it we give it gravitational potential energy mgh. By exerting Fe to push the object up the incline, we do the same amount of work in the ideal frictionless case. So setting the works equal FeL = Frh, we arrive at the ideal mechanical advantage Fr/Fe = L/h shown in the illustration.
