Question:

The cable has a specific weight g (weight/volume) and cross-sectional area A. Assuming the sag s is small, so that the cable€™s length is approximately L and its weight can be distributed uniformly along the horizontal axis, determine the average normal stress in the cable at its lowest point C.

A L/2-
