What is nonlinear load?

It must mean a load that is not constant, or does not follow a straight line relation with some other parameter. For example air resistance- the drag on a vehicle increases as the square of the speed, so the load on the motor increases at a similar rate ( or at least that part of the motor load used to overcome air resistance).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
