The rigid bar is not called a fulcrum! And, by the same token, why is the bar called a bar?
Fulcrum is the point that a lever rests or is supported.
A point is a zero-dimensional object. It has no length, width, height, etc. Coordinates are the numerical location of that point. Point A can be at the coordinates (2,3) on a Cartesian grid.
Foot rests can be bought in a variety of places. One can buy them at furniture stores, home improvement stores, and home supply stores. One may also find foot rests through online retailers.

THE SUBJECT OF VARIATION is more properly the subject of arithmetic, because it rests squarely on the concept of ratio.

Fulcrum is the point that a lever rests or is supported.
*fulcrum but a fulcrum is the point on which a lever rests or is supported and on which it pivots.
The point is known as the fulcrum.
Fulcrum is the part of a lever where the leaver rests. This point is in the middle.

Load = the force of the weight of the lever fulcrum = the point of which the lever rests effort = the force you apply to the lever
Load = the force of the weight of the lever fulcrum = the point of which the lever rests effort = the force you apply to the lever
The lever? There are probably other names for it, but i was always taught the fulcrum, lever, and load. Load closer to fulcrum, easier to lift load. (longer lever= mechanical advantage) This would fall under simple machines in science class.
