A 68-lb child and a 20-lb cardboard box are on an oak beam. Determine the magnitude of the largest shear force (consider both positive and negative values) in the beam. Let a = 19 in., b = 27 in., and c = 44 in.

A composite beam consists of a Southern pine [E = 8.5 GPa] timber that is reinforced on its lower surface by a steel [E = 200 GPa] plate. Assume the following dimensions:b1 = 175 mmd = 375 mmb2 = 125 mmt = 18 mmCalculate the distance to the centroid of the transformed section from the bottom surface of the steel plate.

If Mz = 13,000 lb-ft, find the magnitude of the bending stress at a point H. For the beam cross section, assume b = 6.250 in. c = 2.500 in. d = 4.375 in.t = 0.625 in. The centroid of the cross section is located 2.321 in. above the bottom surface of the beam. The moment of inertia about the z axis is 27.9309 in.4.

A toy block and a cylinder are stacked to form a composite shape. The block has dimensions a = 19 mm and b = 57 mm. The cylinder has a diameter of b/2. Determine the moment of inertia about the horizontal centroidal axis for the shape which is located 44.347 mm above the table.
