Question

\Please help me to do part (c)Part c) Using the shear and moment diagrams created for the beam shown in “c” determine the maximum bending stress created for the largest positive bending moment and the largest negative bending moment. Consider the beam to be a W 12 x 79.

Part a) Draw the shear and bending moment diagrams. Clearly show the values, slopes, and degree of curves (e.g., parabola, 3rd degree polynomial). 10 k 20 k 20 k 75 kN 200 kNm A ܘ C D 8ft8f8ft-7-8ft - 24m 4m—to 4m (b) 75 kN- 25 kN/m 3 k/ft с (0) -24 ft—_ 9ft (d) 10 k 10 k 60 KN 12 kN/m 3 k/ft 200 kNm] IB C D A sht 20 ft - 5m- 1 10m— Part b) Using the shear and moment diagrams created for the beam shown in "a" determine the maximum bending stress created for the largest positive bending moment and the largest negative bending moment. Consider the beam to be rectangular measuring 10 inches wide and 20 inches deep.
