Question

Controls can be made using _____________

(a) wood

(b) copper

(c) steel

(d) flaps

I have been asked this question in an internship interview.

This interesting question is from Materials Selection in chapter Materials Selection of Aerospace Materials & Processes

Answer 1

The correct choice is (c) steel

For explanation I would say: Controls can be made using either steel or aluminium alloys. Controls refer to the control parts of an aircraft like control sticks, torsion tubes, bell-cranks etc. Wood and copper are not used.
