Explanation:
The Hooke's law relation between stress and strain is mathematically represented as
Where 'E' is modulus of elasticity of the material
Now by definition of strain we have
Applying values to obtain strain we get
Thus the stress developed in the material equals
Now by definition of stress we have
Solving for 'D' we get
Answer:
The volume percent of graphite is 9.9%
Explanation:
Given;
weight percent of graphite, C = 3.1wt%
density of ferrite, = 7.9 g/cm³
density of graphite, = 2.3 g/cm³
Determine the mass fraction;
Determine the volume fraction;
Therefore, the volume percent of graphite is 9.9%
