Question

A bend of what angle is considered as a single bend?

(a) 45°

(b) 90°

(c) 180°

(d) 270°

I had been asked this question in homework.

I need to ask this question from Aircraft Materials in section Testing Aircraft Materials of Aerospace Materials & Processes

Answer 1

Correct option is (b) 90°

For explanation: In the reverse bend test, a single bend is usually considered to be 90° in each test. The machine goes both back and forth each time 90°, making a total of 180°, but one bend is considered to be 90°.
