How do you calculate tension in a cable?

To calculate tension in a cable, take the mass of the section of
cable and consider the force applied straight downward due to the
acceleration of gravity. Divide that by two because the cable is
supported at both ends. That is the force applied to one support in
a downward direction. Now, consider the angle of the cable relative
to vertical at the support. Using simple vector analysis, determine
the force in the direction of the cable. That is the tension of the
cable.
If you also calculate the horizontal force vector at the
support, that would be the force pulling the two supports together,
although that is not usually an issue because there is often
another section of cable on the opposite side of the support which
balances the horizontal force vector.
