Chapter III$-1$ Stress analysis

Homework $1$

In case of uniaxial tension, deduce the total stress, normal stress and shear stress on the cross section: $(1)$ perpendicular to the axis of the cylinder $(2)$ has an angle Sita with the horizontal surface, with the direction cosines. The rectangular cartesian system can be defined as vou want.

Give the process to calculate the three principal stress and principal direction with the stress tensor:

Assume a stress tensor, express the stress state using a cubic element, calculate the invariants, principal stresses and corresponding directions.
