- A beam cross section is shown. The dimensions are d = 10.2 in. and t = 0.46 in. The centroid of the cross section is located e = 5.499 in. above the bottom edge of the shape and f= 2.701 in. below the top edge. Calculate the moment of inertial for this cross section. (1) Break the cross section into three parts as shown below. Use the parallel axis theorem to calculate the area moment of inertia for one of the vertical rectangles ((1) or (3)) about the z-axis. +₁ Answer: (2) d 50.66 y a (3) +₁ in.4arrow_forwardFor the loaded beam shown below, find the reactions at A and B then draw the shear force and bending moment diagrams then find the location and value of maximum tensile stress.

The top of the T-shape cross section serves as a flange or compression member in resisting compressive stresses. In a building construction, the T-Shape beam which made of an elastic perfectly plastic material was used and its dimension is shown in Figure 3.2. For the beam indicated, determine the fully plastic moment and shape factor of the beam if the value of E = 200 GPa and o, = 250 MPa.
