Diagram illustrating the offset of strata produced by vertical slipping along an inclined plane, when the fault is oblique with reference to the strata. The dotted outline restores the fault scarp and gives the appearance immediately after faulting, before erosion has removed this portion of the block.

An example of a simple machine. In the figure, AC is the included plane, CB is the height of the plane, BA is its base, and BAC is the angle of inclination or elevation. The power necessary to sustain any weight on an included plane is to the weight as the height of the plane to its length, or as CB to CA.
