(For televisions)
Aspect ratio is the ratio of the width of the television screen to the height.
TVs do not have taper ratios.
(For airplanes)
Aspect ratio is a ratio of the wing span squared to the wing's reference area. This gives you a sense of how thin/slender a wing will appear from the top view of the aircraft. High aspect ratio means a long/extended wing.
b² / S
("b" is wing span, "S" is wing area)
Taper ratio is the ratio of the wingtip's length to the wing root's length. This gives you a sense of the angle the shape of the wing. High taper ratio means a triangular shaped wing.
t/r
("t" is length of the wingtip, "r" is length of wing's root)
The taper ratio of a wing is the ratio between the tipchord and the rootchord: ct/cr
Taper
To calculate shaft taper, measure the diameter at two points along the length of the shaft. Subtract the smaller diameter from the larger diameter to find the taper amount. Then, divide this difference by the length of the taper section to determine the taper per unit length. This result is often expressed as a ratio or in degrees, depending on the application.
The pro taper has the same diameter from the tip to about 12-14 inches toward the joint, at which point it begins to widen. The European taper widens continually and smoothly from the ferrule toward the joint.
Square taper and JIS square taper bottom brackets differ in their dimensions and compatibility with cranksets. Square taper bottom brackets have a 2-degree taper angle, while JIS (Japanese Industrial Standard) square taper bottom brackets have a 1.5-degree taper angle. This difference affects the compatibility of cranksets with the bottom bracket spindle. It is important to match the type of bottom bracket with the corresponding crankset to ensure proper fit and performance.
A cone (n) is a shape whose base is a circle and whose sides taper up to a point. A frond (n) is a compound leaf of a fern or palm or cycad.
The purpose of measuring taper angle is to obtain taper angle
This is the formula for calculating a taper: Large diameter of the taper minus the small Diameter of the taper divided by the length of of the taper will give you the taper per inch. You will also need to know the included angle of the taper if you ar cutting this taper. This formula would be Tangent of the included angle divide by 2.
The recommended torque specification for a square taper bottom bracket installation is typically between 30-50 Nm.
This means that it is the opposite of the normal direction that a taper goes. Example; If a normal taper goes to the left, a reverse taper goes to the right.
A taper is an Elizabethan word for a specific kind of candle.
JIS and ISO square taper bottom brackets differ in their spindle length and taper angle. JIS bottom brackets have a shorter spindle length and a 2-degree taper angle, while ISO bottom brackets have a longer spindle length and a 1.5-degree taper angle. These differences affect compatibility with cranksets and require matching components for proper installation.
