I ran into a issue in my study - I am using the CERM (11th Ed.) and I am having a serious issue determining the Hyperbolic Cosine, cosh and the Constant, c. Ref Chapter 41-19 in determining tension in catenary cables.
My question roots from my practice problems CERM Practice Problems (also the 11th Ed.)
How do you determine the Cosh - as in Practice Problem 1
"Two towers are located on level ground 100ft apart. They support a transmission line with a mass of 2 lbs/ft. The midpoint Sag is 10 ft."
a. What is the midpoint tension?
b. What is the max tension in the transmission line?
I understand the formula they use but am having issues with find the Constant c and Hyperbolic Cosine, cosh
thank you in advance!
