1. Normal stress is defined as force / area . Here sress is inversely proportional to area , Thus staement is FALSE . 2. Stress is basically defined as sigma ( OPTION - 4 ) Option 1 is for shear strain , option 2 is for diameter . 3. For stress calculations , always a material shoul be continous Thus option E is correct . other options like cohesiveness , isotropic , homogeneous are also important but continous property is most important |
If have any doubt please ask me anytime in comments section ... Thank you
