A composite beam consists of a Southern pine [E = 9.0 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 = 16 mmCalculate the distance to the centroid of the transformed section from the bottom surface of the steel plate.

A composite beam consists of a Southern pine [E = 9.0 GPa] timber that is reinforced on its lower surface by a steel [E = 200 GPa] plate. Assume the following dimensions:b1 = 125 mmd = 250 mmb2 = 75 mmt = 14 mmCalculate the distance to the centroid of the transformed section from the bottom surface of the steel plate.

A composite beam consists of a Southern pine [E = 9.0 GPa] timber that is reinforced on its lower surface by a steel [E = 200 GPa] plate. Assume the following dimensions:b1 = 125 mmd = 250 mmb2 = 75 mmt = 18 mmCalculate the distance to the centroid of the transformed section from the bottom surface of the steel plate.

Load P = 1.3 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 0.28 in. and a length of L = 5.7 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.

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.
