Locate the centroid yc of the concrete beam having the tapered cross section shown. Given: a = 100 mm b = 360 mm c = 80 mm d = 300 mm e = 300 mm

Given figure:
All dimensions are in mm
We assume that the origin lies at the point O as shown in the figure above. Now owing to the symmetry about the Y-axis, the x-coordinate of the body will be 0.
In order to evaluate the y-coordinate of the centroid, we ca
y on some calculations and apply the...
