The stresses acting at a point in a two$-$dimensional stress system is shown in figure determine

analytically also verify graphically $($Mohr$$s circle$).$

$1-$ Direction of principal stresses

$2-$ Magnitude of principal stresses

$3-$ Maximum shear stress

$4-$ Mohr$$s Circle NOTE: SOLVE IT IN CLEAR WAY AND WRITING SHOULD BE CLEAR $+$ DRAWING PLEASE.
