For the stress state of the two elements below

$($a$)$ Draw the Mohr circle $($to the scale$)$ and find the pole.

$($b$)$ Show the point on the Mohr circle corresponding to the stress state at plane $A=A^{\text{'}},$

$($c$)$ Find the resultant stress and its obliquity at plane A$-$A$\text{'}.$

$($d$)$ Magnitude and direction of principal Stresses,

$($e$)$ Maximum shear stress and its plane of action.

Given stresses on the two elements shown in the Figure below, find the stresses on plane

A$-$A using Mohr circle distribution in each case.
