  • A meridional ray is a ray that passes through the axis of an optical fiber.
  • A skew ray is a ray that travels in a non-planar zig-zag path and never crosses the axis of an optical fiber.

Where is the world's most skewed arch bridge?

Skew arch bridges of up to 45 degrees are not uncommon and many even exceed that figure. There's a helicoidal skew arch in the U.K. that was built of stone in 1830 to carry the Haggerleazes branch of the Stockton & Darlington Railway over the River Gaunless, which has a skew angle of 63 degrees. In other words, instead of crossing the river at the normal 90 degrees, the railway and river cross at 27 degrees. (90 - 27 = 63) There's a skew arch bridge built to a different principle (it's called a ribbed skew arch) in Harpenden, Hertfordshire, UK that carries the Midland Main Line across Southdown Road at an angle of only 25 degrees, giving the bridge a skew angle of 65 degrees. That's the most skewed arch bridge I know of but there may well be others and if so I'd like to know. (Reference: http:/en.wikipedia.org/wiki/Skew_arch)


What is skew in relationship to parallel bus?

A parallel bus has many wires, and it sends 8 (or more) bits at the same time -- one bit on every wire. Then later it sends 8 more bits at the same time. Even though all 8 bits are started at the same time, the receiver often finds the bit on one wire slightly early and the bit on some other wire slightly late. The difference in time between the first bit to arrive and the last bit to arrive is the bus skew. Because serial buses send only one bit at a time, there is no "other wire". So serial buses do not have bus skew.


How much is skewing angle in three phase induction motor?

the skew angle varies from 0 degrees, depending on how much torque you want at near synchronous speed and how smoothly you want to transition with varying loads most motors all the shorting bars are parallel to shaft. skew is more often for lower current starting in motors that will turn on an off a lot


Do you need to use TC extension wire to connect a thermocouple or can you use shielded cable?

You must use thermocouple wire (of the same type as the thermocouple) to extend the circuit. If you switch to a different wire the point of connection between the two becomes a thermocouple junction itself, and the resulting voltage from that junction will skew your reading. You can use any wire to extend a thermocouple connection if you know the temperature of the junction where the thermocouple wire ends--this becomes the reference junction.


How do you avoid setup and hold time violations?

To avoid setup time violations:The combinational logic between the flip-flops should be optimized to get minimum delay.Redesign the flip-flops to get lesser setup time.Tweak launch flip-flop to have better slew at the clock pin, this will make launch flip-flop to be fast there by helping fixing setup violations.Play with clock skew (useful skews).To avoid hold time violations:By adding delays (using buffers).One can add lockup-latches (in cases where the hold time requirement is very huge, basically to avoid data slip).

What is the difference between meridonal rays and skew rays?

Meridional rays are rays that pass through the optical axis of a system, while skew rays do not. Skew rays travel at an angle to the optical axis, resulting in a more complex path through the optical system.


Can segments and rays be skew lines if they lie in skew lines?

They can be, and are, "skew". If they are not lines, they cannot be "skew lines".


If the rays do not intersect at one point what do this indicate?

It means that they are skew.


What is formed by two rays called?

What is a skew plane?

There is no such thing as a skew plane - in isolation. It can only be skew with reference to something else.


How do you calculate the skew?

Skew applies to the average difference between two timing states of a single signal as it transit from low to high and high to low. Skew is frequently refereed to as the Pulse Width Distortion (tpHL-tpLH). When multiple independent and equal device types are used for parallel data transmission, the skew of each device is important since the max and mix Skew can establish the maximum data rate.


Do lines that skew intersect?

No. Skew lines do not intersect

Are skew lines in the same plane?

No. Skew lines must be in different planes. Skew lines have no common points (they never cross).
