Final answer:
A generally accepted dynamic bend radius is used when the bend radius of a cable is not known. The specific value of the dynamic bend radius depends on factors such as the cable material and diameter. Following the manufacturer's guidelines is important to ensure the cable's proper functioning.
Step-by-step explanation:
When the bend radius of a cable is not known, a generally accepted dynamic bend radius is typically used. A dynamic bend radius is the minimum radius at which a cable can be bent without damaging its performance or function.
The specific value of the dynamic bend radius depends on factors such as the material of the cable, its diameter, and the intended use. For example, in the case of fiber optic cables, the generally accepted dynamic bend radius is around 10 times the cable's outer diameter.
It is important to follow the manufacturer's specifications and guidelines for bend radius to ensure the proper functioning and longevity of the cable.
