RE: Cable tension formulas kslee1000 (Civil/Environmental) 4 Apr 09 09:12 I afraid there is no "less" painful way to handle this analysis, unless there is a black box program claims it can do it, and results were proven true (quite a few structural programs had flunked in this regard - foundamental mechanics, in the past). A turnbuckle is not required to tension this Zip Line; there are other methods described in the Users Manual (turnbuckles only give you 6 or 9 inches of tensioning stroke, with methods described in manual you can easily take up 3 feet of slack). Long zip line project. So it was believed for a long time. The easiest way to calculate how high off the ground should the cable be is by calculating the height of the finishing point first and then figuring out the height of the starting point. You will need to provide the information requested in the drop-down menus that follow. Structural stretch is the lengthening of the lay in the construction of cable and wire rope as the individual wires adjust under load. Line Tension. However, material prices run between $1 to $7 per linear ft. So, imagine the speed line is 10,000lb breaking strain rope, you've tightened it up at say a 45 deg angle, you lower. Expect these prices to rise for additional floor levels and complexity of the job. Cool so tension=weight x lenght of line / 4xsag so for a 500lb load on a 600 zip line with 20' sag the tension is 500x600/80=3750lbs which should be well within safety limits of the 5/8 tenex I ordered with test of 17000. Elevator - Force and Power - Required force and power to lift an elevator ; Force and Tension in Rope due to Angle - Reduced load capacity in ropes, cables or lines - due to angle; Manila Rope - Strength - Manila 3-strand rope - minimum breaking.
