Question

The modulus of elasticity of pure magnesium is __________

(a) 6,500,000 p.s.i

(b) 4,350,000 p.s.i

(c) 16500 ksi

(d) 330,00,000 p.s.i

I got this question in my homework.

Question is from Applications and Properties of Magnesium and it’s alloys in chapter Magnesium Alloys of Aerospace Materials & Processes

Answer 1

Right choice is (a) 6,500,000 p.s.i

To elaborate: The modulus of elasticity can be described as the resistance of a substance to elastic deformation when it is subjected to stress. The modulus of elasticity of magnesium is 6,500,000 p.s.i and that of aluminium is 4,350,000 p.s.i.
