The mathematical term that refers to a spiral is "spiral" itself, but there are specific types, such as the "Archimedean spiral," which is characterized by a constant distance between successive turns, and the "logarithmic spiral," where the distance between turns increases exponentially. Spirals can be described using polar coordinates, where the radius is a function of the angle. They are commonly found in nature, art, and various fields of mathematics.
An arithmetic spiral is a spiral which increases in distance from its point of origin at a constant rate.
What is the maxcimam allowable distence between two spirals of the concertina fencing for a four feet dimater spiral?
The bar.
The separating distance between spiral tracks on a Blu-ray disc is typically measured in micrometers (μm). It is determined by the track pitch, which is the distance between the centerlines of two adjacent tracks. The track pitch for a Blu-ray disc is usually around 320 nm (nanometers), which is equivalent to 0.32 μm. The track pitch is critical for ensuring accurate data storage and retrieval on the disc.
spiral model is just like incremental model but in spiral emphasize is on risk analysis.
The spiral bands of a hurricanes are relatively narrow areas of heavy rain that spiral into the eye wall of a hurricane. Rain between these bands is lighter.
The lined paper is smaller lines and the spiral is bigger lines
The arms of the Spiral Galaxy are mostly located in one plane.
As the name suggests, the barred spiral galaxy has a barred central core.See related link for a pictorial
A grand design spiral galaxy (like Whirlpool Galaxy) has prominent and well defined spiral arms, whereas a flocculent galaxy (like Sunflower Galaxy) has short segments of spiral structure, "fluffy" in appearance, but without the dramatic well defined spiral arms of a grand design spiral.
spiral perm is rolled vertical and reg perm is rolled horizontal, I think.
