Please answer and show graphAngle:

$2.$ Stress in $3$D $[$value $=4]$

a$)$ Draw the $3$D Mohr's diagram for the following stress element. Use arrows to clearly label points on the Mohr's diagram that correspond to the principal stresses $({}_1,{}_2,{}_3),$ max shear stresses $({}_{\text{m}\text{a}\text{x}}),$ and the surfaces normal to the $x,y,$ and z coordinate axis $($label as x $-$axis, y $-$axis, z $-$axis$).$

b$)$ Draw the $3$D Mohr's diagram for the following stress element. Use arrows to clearly label points on the Mohr's diagram that correspond to the principal stresses $({}_1,{}_2,{}_3),$ max shear stresses $({}_{\text{m}\text{a}\text{x}}),$ and the surfaces normal to the $x,y,$ and z coordinate axis $($label as x $-$axis, y $-$axis, z $-$axis$).$

c$)$ Draw the $3$D Mohr's circle for the following stress element $($cube placed on the bottom of the ocean$).$
