Webthe location of the centroid for different beam shapes? The I-beam (top) or T -beam (bottom) shown are commonly used in building various types of structures. When doing a stress or deflection analysis for a beam, the location of its centroid is very important. Webdetermining the shear stress in a beam is calculating the value of Q(y o), the first moment of area about the centroid for the area above or below a cut located a distance y o from the centroid. Calculating Q(y 0) Hide Text 7 Again, what we mean by the term Q(y o) is the value of the integral of y • dA over the area A', where A' is the area
