Load P = 8.0 lb is produced at the nylon tip of a Regal Tip Quantum 1000 drumstick as a percussionist strikes a drumhead. The hickory shaft has a diameter of 0.53 in. and a length of L = 10.0 in. from the center of the tip to the percussionist’s hand. Assuming the percussionist’s hand acts like a fixed support and that the shaft has a constant diameter, determine the magnitude of the maximum horizontal shear stress in the shaft.
