| in. | Cable diameter, for your reference only |
| lbs./ft. | Cable weight per foot, not the horizontal weight per foot. If applicable, include ice load, etc. |
| sq.in. | Metallic area of the cable, leave zero if the stretch of the cable is not required |
| ft. | Horizontal span between the bottom support lug and the top support lug |
| ft. | Vertical height between the two support lugs. This input value can be zero, ie for a cableway |
| ft. | X, a horizontal distance from the bottom support lug to a point in question on the cable |
| lbs. | Horizontal tension in the cable. If this value is not known, estimate it at ~10,000lbs for a first try in solving for a specific sag, tension at the deadman, etc. |
