Critical Stress Element and complex loading. The following loads have been applied to a structure.

a$.$ Draw an arrow that clearly approximates the location of the CSE $($maximum shear$)$ on the crosssection at A$.[3$ pts$]$

Cross$-$Section at A

b$.$ Based on the tractions that would form on the CSE, what type of stress state would exist on the CSE $($circle one below$).[2$ pts$]$

i$.$ Uniaxial $(2$ principal stresses are zero$)$

ii$.$ Planar $(1$ principal stress is zero$)$

iii. Triaxial $($no principal stresses are zero$)$
