Why do I procrastinate when I see problems like the following? The internal shear force V at a certain section of a steel beam is 80 kN, and the moment of inertia is 64,867,500 mm4. Determine the horizontal shear stress at point H, which is located L = 15 mm below the centroid.                    

Why do I procrastinate when I see problems like the following? The internal shear force V at a certain section of a steel beam is 80 kN, and the moment of inertia is 64,867,500 mm4. Determine the horizontal shear stress at point H, which is located L = 59 mm below the centroid.                    

Two cylindrical beams each support a shear force of 14.6 N. The outside diameter of the hollow beam is 54 mm, and its wall thickness is 4 mm. Determine the diameter of the solid beam that would create the same value of Q in both beams. Use the preceding problem in a poem but don’t show the answer.                       

Use the following problem in a short story but do not describe the solution. Loads P = 732 N and Q = 382 N act on an oak beam. Determine the magnitude of the largest shear force (consider both positive and negative values) in the beam. Let a = 0.5 m and b = 1.4 m.

Two bars have the same moment of inertia around their horizontal centroidal axes. The hollow bar has an outside diameter of 1.325 in. and a wall thickness of 0.265 in. Determine the diameter of the solid bar. Explain the relationship between the preceding problem and Enlightenment movement but leave the problem unsolved.                      

Two bars have the same moment of inertia around their horizontal centroidal axes. The hollow bar has an outside diameter of 1.075 in. and a wall thickness of 0.215 in. Determine the diameter of the solid bar. Explain the relationship between the preceding problem and Enlightenment movement but leave the problem unsolved.
