Extracted text: 8. A 9.00 m span simply supported beam carries a uniformly distributed load of 100 kN/m and point load of 400 kN. The point load is applied at 6.00 m from one end of the beam. as shown below. 400 kN 200 100 kN/m 700 dia = 50 150 6.00 m 100 150 400 9.00 m CROSS - SECTION Determine: The highest shear force At this section, compute the average shear stress At this section, identify the maximum shear stress i. ii. ii. Answers: Note: Student should draw the SFD, BMD and Deflected shape. Use the coordinates given below to check answers. (i) SFD: (0.00m, 583KN): (5.83m, 0.00KN); (6.00m, -16.7kN), (6.00m, -417KN); (9.00m, -717KN) (ii) fv, average = V/A = 717 x 103 N/(243.04 x 103 mm2) = 2.95 MPa (iii) y = 432.2 mm from base; or 567.8 mm from top. At N.A., Q = 200 x 567.8 x 567.8/2 = 32.24 x 106 mm3. fy = VQ/(It) where V = 717 kN, Q = 32.24 x 106 mm³; Ix = 22.08 x 10° mm“ and t = 200 mm which yields fy = = 5.23 MPa Screenshot
