Answer:
The theoretical fracture strength of a brittle material is 26465.29 MPa.
Explanation:
Given that,
Length = 0.54 mm
Radius curvature
Stress = 1050 MPa
We need to calculate the theoretical fracture strength of a brittle material
Using formula of strength
Where, l = length of the crack
= tip radius of curvature
Put the value into the formula
Hence, The theoretical fracture strength of a brittle material is 26465.29 MPa.
The mass of Mg-24 is 24.30506 amu, it contains 12 protons and 12 neutrons.
Theoretical mass of Mg-24:
The theoretical mass of Mg-24 is:
Hydrogen atom mass = 12 × 1.00728 amu = 12.0874 amu
Neutron mass = 12 x 1.008665 amu = 12.104 amu
Theoretical mass = Hydrogen atom mass + Neutron mass = 24.1913 amu
Note that the mass defect is:
Mass defect = Actual mass - Theoretical mass : 24.30506 amu- 24.1913 amu= 0.11376 amu
Calculating the binding energy per nucleon:
So approximately 4.41294 Mev/necleon
