Load P = 0.3 lb is produced at the tip of a mallet as a percussionist strikes an instrument. The tip of the mallet is a rubber ball. The wooden shaft has a diameter of 0.27 in. and a length of L = 4.2 in. from the center of the tip to the percussionist’s hand. Assuming the percussionist’s hand acts like a fixed support, determine the maximum bending stress in the shaft.

Load P = 0.6 lb is produced at the tip of a mallet as a percussionist strikes an instrument. The tip of the mallet is a rubber ball. The wooden shaft has a diameter of 0.28 in. and a length of L = 5.1 in. from the center of the tip to the percussionist’s hand. Assuming the percussionist’s hand acts like a fixed support, determine the maximum bending stress in the shaft.

If Mz = 3,000 lb-ft, find the magnitude of the bending stress at a point H. For the beam cross section, assume b = 3.750 in. c = 1.500 in. d = 2.625 in.t = 0.375 in. The centroid of the cross section is located 1.393 in. above the bottom surface of the beam. The moment of inertia about the z axis is 3.6198 in.4.
