My daughter is graduate math student and I am scratching my head when she asks me a question for a practical purpose or equation ... I have no idea how they teach some of this highly technical "mathematically unravelling the universe" stuff yet they need to ask basic questions .......

There's all sorts of engineering physics text- and study-problems available to show what is possible, however one example would be:
"If one-fourth of an electric cable of length 'L' and uniform density 'D' is hanging over the edge of an icy cable tray, how much work does an electrician have to do to slowly pull that last part of it up onto the tray?" -note that the length of the cable is constantly changing after he starts working on it, so the force he applies always varies.
