1. The problem statement, all variables and given/known data Compute the cable tension at the midpoint, (L/2), the quarterpoint (L/4), and support for a 1600 foot span with a sag at the midpoint of 100 feet, when the cable is loaded with 10 kips/foot spread uniformly along the horizontal line. 2. Relevant equations 3. The attempt at a solution I have no clue what so ever, of what to do. I'm in an introductory engineering class.
