An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade.
Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved. The mechanical advantage of an inclined plane, the factor by which the force is reduced, is equal to the ratio of the length of the sloped surface to the height it spans. Due to conservation of energy, the same amount of mechanical energy (work) is required to lift a given object by a given vertical distance, disregarding losses from friction, but the inclined plane allows the same work to be done with a smaller force exerted over a greater distance.
The angle of friction, also sometimes called the angle of repose, is the maximum angle at which a load can rest motionless on an inclined plane due to friction, without sliding down. This angle is equal to the arctangent of the coefficient of static friction μs between the surfaces.
Two other simple machines are often considered to be derived from the inclined plane. The wedge can be considered a moving inclined plane or two inclined planes connected at the base. The screw consists of a narrow inclined plane wrapped around a cylinder.
The term may also refer to a specific implementation; a straight ramp cut into a steep hillside for transporting goods up and down the hill. It may include cars on rails or pulled up by a cable system; a funicular or cable railway, such as the Johnstown Inclined Plane.
A while back, I bought an AK47 M64 kit. Originally I welded up the cut (milled) receiver but it never worked very well, to say nothing of the weld strength (or lack of).
Persistence paid off and a few years back, I got my AK a genuine milled receiver, reassembled the gun, adjusted the head...
For our 1911 gurus, is this a timing/mag issue or a COAL issue? Hollows and LFN both catch on the bottom edge of the barrel at the bottom of the ramp as it's feeding. Is this a nose-dive problem with the mag or do I have a bigger issue? 1911 GCNM vintage 70's, not 'smithed, bubba or...
I'm getting out of motorcycles for now, so I'm selling a few things that I will no longer need.
This is a Motorcycle/ATV ramp. I bought it for my Aprilia build project, and it was used during that build. I no longer need it. I've look around online and found that the cheapest one new is...
