Hi, my problem is this; I am designing a cable camera system to film downhill pursuits. I need to calculate how much tension is required to hang a cable over a 100m span with no more that 0.5m sag in the middle, when is it fixed at two point, both at the same hight. From the research I have done I have found out that a catenary curve will calculate the sag in a chain when subject to gravity. I am having trouble working through the equations associated with this and would appreciate some help working though it with me.
Many thanks in advance,
