In structural geology, rake (or pitch) is formally defined as "the angle between a line [or a feature] and the strike line of the plane in which it is found", measured on the plane. The three-dimensional orientation of a line can be described with just a plunge and trend.
In geology, strike and dip is a measurement convention used to describe the plane orientation or attitude of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle ) measured downward from horizontal. [ 1 ]
A motorcycle or bicycle fork rake, the angle at which the forks are angled down towards the ground; Rake angle in machining and sawing, the angle of a cutting head; Rake (geology), the angle at which one rock moves against another in a geological fault; Rake (theatre), the slope of a stage angled towards the audience for a better view
Rake is measured by placing a protractor flat on the planar surface, with the flat edge horizontal and measuring the angle of the lineation clockwise from horizontal. The orientation of the lineation can then be calculated from the rake and strike-dip information of the plane it was measured from, using a stereographic projection.
Pitch, or rake, in geology, the angle between a line and the strike of the plane on which it was found; Electromagnetism. Pitch angle (particle motion) ...
Rake, the caster angle of a bicycle or motorcycle; Rake, the difference between the front and rear ride heights of a car; Rake (train), a line of coupled passenger coaches, or freight wagons, or railcars (excluding the locomotive) that typically move together
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth 's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of ...
A schematic showing positive (left) and negative (right) rake angles. In machining, the rake angle is a parameter used in various cutting processes, describing the angle of the cutting face relative to the workpiece. There are three types of rake angles: positive, zero or neutral, and negative. Positive rake: A tool has a positive rake when the ...
