A composite beam consists of a Southern pine timber that is reinforced on its lower surface by a steel 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.

Load P = 1.9 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 = 4.9 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 = 1.6 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 0.25 in. and a length of L = 4.4 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.
