(c) 50

(d) 26

I got this question in an online quiz.

My question is taken from Aircraft Materials in division Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

Right option is (c) 50

To explain I would say: The maximum speed up to which the bending experiment can be conducted in the reverse band test is 50 bends per minute. This should be done while considering how it could be prone to heating.
