Date: 16/08/2020

After watching this video all doubt of principal stress will clear. 
1. First described the definition of Principal stress and Plane. 
2. also explained how this is related to normal stress. 
3. to explain the relationship between normal stress and principal stress few examples solved using MATLAB and explain how normal stress varies with different angles. 
4. Finally, the derivation of principal stress and plane is performed.
