The number of tines on tools varies widely – a pitchfork may have just two, a garden fork may have four, and a rake or harrow many. Tines may be blunt, such as those on a fork used as an eating utensil; or sharp, as on a pitchfork; or even barbed, as on a trident. The terms tine and prong are synonymous. A tooth of a comb is a tine.
The Sears–Haack body is the shape with the lowest theoretical wave drag in supersonic flow, for a slender solid body of revolution with a given body length and volume. The mathematical derivation assumes small-disturbance (linearized) supersonic flow, which is governed by the Prandtl–Glauert equation .
The pitchfork is often used in lieu of the visually similar weapon, the trident, in popular portrayals and satire of Christian demonology. Many humorous cartoons, both animated and otherwise, feature a caricature of a demon ostensibly wielding a "pitchfork" (often actually a trident) sitting on one shoulder of a protagonist, opposite an angel ...
Tuning fork by John Walker stamped with note (E) and frequency in hertz (659) A tuning fork is an acoustic resonator in the form of a two-pronged fork with the prongs formed from a U-shaped bar of elastic metal (usually steel).
In the adjacent diagram, (a) and (b) are referred to as having an offset below center, while those in (c) and (d) have an offset above center. In determining the direction of offset, it is customary to look at the gear with the pinion at the right. For below center offset the pinion has a left hand spiral, and for above center offset the pinion ...
Like many polearms, the military fork traces its lineage to an agricultural tool, in this case the pitchfork. [1] Unlike a trident used for fishing, the military fork was rarely barbed and normally consisted only of two tines (prongs) which were straight compared to the original pitchfork. The pair of tines usually ran parallel or slightly flared.
Garden fork. A garden fork, spading fork, or digging fork (in the past also an asparagus fork, [1] the same name as a very different utensil) is a gardening implement, with a handle and a square-shouldered head featuring several (usually four) short, sturdy tines.
Comparison between tunings: Pythagorean, equal-tempered, quarter-comma meantone, and others.For each, the common origin is arbitrarily chosen as C. The degrees are arranged in the order or the cycle of fifths; as in each of these tunings except just intonation all fifths are of the same size, the tunings appear as straight lines, the slope indicating the relative tempering with respect to ...
