    Solution:

    Locate the centroid y for the beam's cross-sectional area. Question 5 5 pts Locate the centroid...

     
    x = 300mm
     
    y1 = 240 +60 = 300mm
    y = (a1y1 + a2y2) / (a1 + a2)
    y2 = 240/2 = 120mm
    y =[(72000 x 300 ) +(29800 x 120)] / (72000 +28800) = 248.57mm
    y ∼ 249mm
     
    The correct answer is 249
