A plate and angle girder is fabricated by riveting the short legs of four (4) angles to a web plate 1000 mm x 10 mm to form a section 1020 mm deep. Cover plates each 300 mm x 10 mm are then riveted to the flange angles making the overall height to be 1040 mm. Determine the following: a.) location of the centroid b.) centroidal moment of inertia c.) Polar moment of inertia with respect to the centroid d.) second moment of area with respect to the x and y axis e.) The section modulus(Sx and Sy) f.) radius of gyration (ry and rx). [NOTE: Description of angles are given by the table for each student.]
