          Which of the following equations will determine the centroidal x-axis for the beam cross sections shown in the Figure below?
0.441"
S 200 x 34
A = 6.77 in2
12.5"
y
W 310 x 52
A = 10.3 in2
A.
$$ \bar{y} = \frac{6.77 \left( 12.5 + \frac{0.441}{2} \right) + 10.3 \left( \frac{12.5}{2} \right)}{6.77 + 10.3} \text{ in.} $$
B.
$$ \bar{y} = \frac{6.77(12.5) + 10.3(12.5)}{6.77 + 10.3} \text{ in.} $$
C.
$$ \bar{y} = \frac{6.77 \left( \frac{0.441}{2} \right) + 10.3 \left( \frac{12.5}{2} \right)}{6.77 + 10.3} \text{ in.} $$
D.
$$ \bar{y} = 6.77 \left( 12.5 - \frac{0.441}{2} \right) + 10.3 \left( \frac{12.5}{2} \right) \text{ in.} $$
E.
$$ \bar{y} = \frac{6.77(12.5 + 0.441) + 10.3(12.5)}{6.77 + 10.3} \text{ in.} $$
