The rectangular plate is deformed into the shape shown by the dashed lines. Suppose that \( a=260 \mathrm{~mm} \) and \( b=390 \mathrm{~mm} \) ( Figure 1) Determine the average normal strain along diagonal \( B D \). Express your answer using three significant figures. Part B Determine the average shear strain \( \gamma_{x y} \) at corner \( B \) relative to the \( x, y \) axes.. Express your answer to three significant figures and include the appropriate units.
