flat plate $ABCD$ distorts into the dashed shape $A{B}^{?}{C}^{?}D$ shown after a load is applied with $a=146.0\mathrm{mm},b=51.0\mathrm{mm},g=13.0\mathrm{mm},f=16.0\mathrm{mm}$ Part A - Average normal strain along $AC$ Determine the average normal strain ${\left({?}_{AC}\right)}_{\text{avg }}$ along $AC$ after the load has been applied. Express the average normal strain in millimeters per millimeter to three significant figures. Determine the average shear strain ${?}_{xy}$ at $A$ relative to the $x$ and $y$ axes. Express the average shear strain in radians to three significant figures. Part C - Average shear strain at point $C$ Determine the average shear strain ${?}_{xy}$ at point $C$ relative to the $x$ and $y$ axes after deformation. Express the average shear strain in radians to three significant figures.
