Question

It is usually preferred for shop bending to take all the present bends ________ grain.

(a) across

(b) above

(c) below

(d) parallel

The question was posed to me at a job interview.

Asked question is from Aircraft Materials topic in division Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

The correct option is (a) across

To explain I would say: In the case of shop bending, it is usually preferred that all the bends be made across the grain. Once the test specimen passes the bending test, it is assured that the material is of good quality and there is a diminished possibility of cracking.
