Yes, if you wanted to know how much tension you're putting on the cable, you'd need to know the deflection angle from a straight line connecting the end points in addition to the force applied. The attached example assumes a perpendicular force at the midpoint of the cable's length. With less of a deflection angle (tight rigged cable), you get a much higher tension for a given force.red wrote:From a technical standpoint, if a cable is rigged straight and tight, deflecting the cable by a handspan can put enormous loads on the cable. A cable rigged slack can be deflected by a handspan and that will put a relatively small load on the cable. It's a function relating to trigonometry.
