Energy stored in a cable? (A Level CW)

    Energy stored in a cable?? (A Level CW)

    Why is the energy stored in a steel cable used for towing gliders so small? And is there an equation that could show this?

    It's the energy store in a spring.
    The cable doesn't stretch very much - that's deliberate so that there isn't much energy stored.

    Well, I can think of a good reason why the two pilots would not want a lot of energy stored in that cable...

    Think of what happens when that cable does break.

    ..or is simply released, as per routine.
