Question

Which one of the following is true in a wide range of construction materials?

Density varies by five orders of magnitude

 

Stiffness varies by five orders of magnitude

 

Strength varies by five orders of magnitude

 

Fracture energy varies by five orders of magnitude​

Answer 1

Answer:

Strength varies by five orders of magnitude

Explanation:

Answer 2

Out of the given four options, 'Fracture energy varies by five orders of magnitude​' is the correct option. So, option (iv) is the answer here.

• The range of properties of a material for construction purpose is very broad.
• According to this wide range, Density varies by two orders of magnitude.
• Stiffness varies by two orders of magnitude.
• Strength varies by three orders of magnitude.
• Fracture energy varies by five orders of magnitude​.
