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 ...
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
A rack and pinion has roughly the same purpose as a worm gear with a rack replacing the gear, in that both convert torque to linear force. However the rack and pinion generally provides higher linear speed — since a full turn of the pinion displaces the rack by an amount equal to the pinion's pitch circle whereas a full rotation of the worm screw only displaces the rack by one tooth width.
The angle of the sloped arm remains constant throughout (traces a cone), and setting a different angle varies the pitch of the spiral. This device provides a high degree of precision, depending on the precision with which the device is machined (machining a precise helical screw thread is a related challenge).
In motorcycles, the steering axis angle is measured from the vertical and called the caster angle, rake angle, or just rake; [5] a 0° rake is therefore vertical. For example, Moto Guzzi [6] offers: a 2007 Breva V 1100 with a rake of 25°30′ (25.5 degrees) a 2007 Nevada Classic 750 with a rake of 27.5°
The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform.It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle.A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform.
The three-dimensional orientation of a line can be described with just a plunge and trend. The rake is a useful description of a line because often (in geology) features (lines) follow along a planar surface. In these cases the rake can be used to describe the line's orientation in three dimensions relative to that planar surface.
These angles are calculated from a standard set of tables that describe the relationship between the take-off angle and the distance between the focus and the observing station. By convention, filled symbols plot data from stations where the P wave first motion recorded was up (a compressive wave), hollow symbols for down (a tensional wave ...
