Question

The ultimate tensile strength of soft copper is __________

(a) 63000 psi

(b) 45000 psi

(c) 29000 psi

(d) 50000 psi

I have been asked this question in class test.

Question is taken from Copper and its Alloys topic in division Copper and its Alloys of Aerospace Materials & Processes

Answer 1

Correct choice is (c) 29000 psi

The best I can explain: The ultimate tensile strength of an element is also sometimes called the tensile strength of a material. The ultimate tensile strength of soft copper is 29000 pounds-force per square inch and that of aluminium is 45000 psi.
