comment Can you punch a hole in an A4 sheet of paper with your hand?
A newspaper has a low bursting strength. The line where it is folded is a structural weakness. The trick even can be done with a newspaper in free fall - an archievement even for an martial arts artist.

comment Optimal size of a windmill for a given windspeed

Here on PSE you find questions for "blade and wind" like a windmill with weighted blades or the homework hint for the work of a windmill. What have you tried to solve the problem?
