Consider the beam's cross-sectional area shown in Part \( A \) (Eigure 1). Suppose that \( a=390 \mathrm{~mm}, b=520 \mathrm{~mm} \), \( c=260 \) IMIIl Determine the location \( \bar{y} \) of the centroid for the beam's cross-5ectional area. Express your answer to three significant figures and include the appropriate units.
