The radius of the curve of the inner edge of the bends shall be at least 6 times the external diameter for armoured cable.
The term "pipe bending radius 40D" refers to the minimum radius at which a pipe can be bent, where "D" represents the diameter of the pipe. Therefore, a 40D bend means the bending radius is 40 times the pipe's diameter. For example, if the pipe has a diameter of 2 inches, the minimum bending radius would be 80 inches. This specification helps ensure the integrity and performance of the pipe during bending, preventing kinks or damage.
The recommended minimum bending radius for conduit bends is typically 5 times the diameter of the conduit.

I believe you want to know the MINIMUM bending radius of sheet metal. The maximum bend would be 180 degrees.
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.
Typically, wires have a bend radius of 10 times the diameter of the wire. Measuring the inside. This is basically to prevent injury or changes in impedance at the bend. Also note that the tighter the bend can damage the insulation in coaxial or triaxial cables and cause lower dielectric strength between layers. Best to install cables where ripples don't form on the surface and moderate force is recommended. MIL-W-5088 has more information.
The formula to calculate the minimum bending radius for steel is: Minimum Bending Radius = (T * Width) / (2 * K), where T is the thickness of the steel, Width is the overall width of the bend, and K is a factor based on the steel's tensile strength and type of steel.
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
The minimum bending radius for a nonshielded cable is typically 8 to 10 times the diameter of the cable. For a cable with a 1.5-inch diameter, this would mean a minimum bending radius of 12 to 15 inches. Therefore, the closest correct answer is B, 12.0 inches.
4 times the diameter of the cable
Every bending mechanism gets governed by the simple bending equation M/I=F/y=E/R
