Name:

Problem One: $(20$ Points$)$ For the strain state $lo{n}_{}=180,lo{n}_{yy}=90$ and $lo{n}_{xy}=50($units are in $\frac{m}{m}).$ Plot $2$D

and $3$D Mohr's circles and Compute the principal strains and maximum shear strains using both approaches.

Also, identify the principal strains and maximum shear strains on each circle. Please make sure to label your

axes correctly. All plot MUST be to scale.
