Every bending mechanism gets governed by the simple bending equation M/I=F/y=E/R
The RADIUS of a 5D pipe bend is actually what is 5 times the nominal diameter. So if you had a 10" diameter pipe, the radius of the centerline of the bend would be 50 inches.
" All bends are elbows but all elbows are not bends." Infact, the pipe is bent to form an elbow. Elbows are pre-fabricated and are firm in design. There are issues with bends since the tickness at the bend radius reduces as we bend the pipe. Sharp bends are normally called Elbows. Bends typically have a minimum bending radius of 1.5 times pipe radius (R). If this bending radius is less than 1.5R, it is called Elbow. Reference to any international / industry standard need to be traced. 1.5, 3 & 4.5 R are the most common bending radii in industry.
steam it and use a home made jig or wet it
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.

It depends on the cable. 0 to 5000 volts the minimum bending radius is 6 x diameter of the cable. Above 5000 volts the minimum bending radius is 8 x the diameter of the cable.
4 times the diameter of the cable

The radius of the curve of the inner edge of the bends shall be at least 6 times the external diameter for armoured cable.
For Unshielded cables, it will 8 multiplies cable diameter and for shielded cables, it is 12 multiplies the cable diameter. However, the smaller the bend radius, the greater is the material flexibility.RegardsKelechi
Four times the outer jacket diameter.
Use the curvature of a tennis ball as a good guide. Try not to bend fiber cables any more than this. The maximum bend (called the maximum bend radius) for any fibre optic cable is determined by the manufacturer, and improvements are being made all of the time. With todays cables, if you bend a fiber optic cable 90 degrees (so it is shaped like the letter L) you will surely damage it. You want to have smooth, gradual curves, and don't go beyond the radius of a tennis ball.

I believe you want to know the MINIMUM bending radius of sheet metal. The maximum bend would be 180 degrees.
The transmission is unreliable after the bend radius is exceeded.
