Cables (Posted on 2024-03-22)

A flexible cable was hung across the Black Canyon between two points that were exactly 1 km apart and at the same elevation.

During the cool night the cable length was calculated to contract by .2 meters. The cable dip was actually measured to decrease by .2 meters!

What is the length of the cable after cooling?

When the length shrinks from 1117.444 meters to 1117.244 meters, the dip decreases from 218.3 meters to 218.1 meters. So the length of the cable after cooling is 1117.244 meters.
For an explanation, refer to the solution submitted by Charlie in this location.
