Problem 3. The cantilever beam AB shown in the figure supports a concentrated load and a couple. Draw the shear-force and bending moment diagrams for this beam. Calculate the maximum bending stress due to the loading if the beam has a rectangular cross section with width b = 8 in and height h = 16 in. 200 lb 400 lb-ft A B 16 in. 5 ft 5 ft 8 in.

Step 1
- Since the beam is cantilevered, the reactions at point A will include a vertical reaction force \( R_A \), a horizontal reaction force (which is zero in this case as there are no horizontal loads), and a moment \( M_A \). Show more…
