strength of materials

What are the types of possible stresses:-
tensile:- Pulling force on both ends of rod
compression:- pushing force on both sides
shear:- parallel forces applied at different plane of action
torsion:- twisting force

Engineering stress:- F/A(i)

engineering strain:- l(f)-l(i)/l(i)

here F= Force , A(i)= initial area ,l(f)= final length ,l(i)=intial length
