In the area of industrial pipe fittings:
Long radius 90 deg elbow has a take off dimension of one and one half times
the nominal diameter of the pipe. Ex-4 inch pipe has an actual diameter of 4.5,
for the elbow the take off dimension would be 4"*1.5=6".
The short radius elbow take off dimension is the same as the nominal size, 4".
To add to the point, a short radius elbow can be used typically where space is a constraint. Hence fluid flow is also restricted in this case unlike in case using of Long Elbow.

You may be looking for the difference between Climb vs Conventional milling. Also known as Down milling and Up milling respectively. In short, the difference is the direction that the teeth of the cutting tool move relative to the material. This can primarily affect smoothness of resulting cut, tool life, and the force on the machine and material. Better description can be found in these links: http://en.wikipedia.org/wiki/Milling_cutter#Conventional_milling_versus_climb_milling http://clinetoolmexico.com/pdf/fresado_tecnica.pdf
A longer fin has increased aerodynamic drag. The geometric relationship between the drag caused by the fins and the center of gravity of the rocket determine the stability of the rocket in flight. Less aerodynamic drag means the rocket can go higher or farther, but it also means the rocket is less stable in flight. This tradeoff has to be considered in the design of the rocket.
A drill/tap center is a specialized VMC. They are typically relatively small, 30 taper machines - lightweight and very fast. They excel in applications with light milling, multiple tools, and short cycle times. The surfacing, drilling, and tapping of casting mating surfaces is a good example. Check out this article for some more info on the link below.
A dynamic load arises from the acceleration or deceleration of a "static" load (mass). A shock load occurs when this acceleration or deceleration is very large and the the time frame is very short.
The difference between the 2 is length and curvature. A short radius elbow offers a tighter turn than the long radius. The short radius elbow is cheaper and will fit into a tighter space.
ow can i know the radius of short radius elbow 45 & 90
No, the radius is a long bone. It is one of the two bones in the forearm, between the elbow and the wrist. Short bones are typically found in the wrists and ankles.
It depends where the pipe is heading, flow is better in along radius, but sometimes there is no room for it.
If your elbow is a short radius it is 1 times your nominal pipe diameter. If it is a long radius it is 1 1/2 times your nominal pipe diameter.show me the exact pattern of long radius
4 1/2 inch
If radius is short it is 1 times pipe diameter. If it is a long radius it is 1.5 times nominal pipe diameter.

Short Radius 90 degree elbows are the same as pipe size.... Long Radius 90's are pipe size times 1.5.... so a 6" (SR) elbow is 6"... a 6" (LR) elbow would be 9"
8"45%. 8421 ad 2nd & last #= face to center
6 inch or 4 inch if it's a short radius
The elbow joint is connected by a short connective tissue called the annular ligament, which stabilizes the joint and allows for rotation of the radius around the ulna.
