hi~ i need to determine the tension a in the equation of the hanging cable y=acosh(x-h)/a+k with a known length and known location of end points. i figured out how to determine the horizontal translation h but i need a in order to do it and to have the complete equation. this is for a computer simulation where the weight of the cable is not important. this is why i condensed tension in the formula down to a. if the weight is a requirement then it can be set, in which case i would need to find the horizontal force acting on the cable. is it possible to find the tension with the given information?
