Load P = 10.6 lb is produced at the nylon tip of a Vic Firth American Classic Jazz 8D drumstick as a percussionist strikes a drumhead. The hickory shaft has a diameter of 0.52 in. and a length of L = 10.3 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.

Two cylindrical beams each support a shear force of 10.0 N. The outside diameter of the hollow beam is 76 mm, and its wall thickness is 6 mm. Determine the diameter of the solid beam that would create the same maximum horizontal shear stress in both beams.

A polymer tee beam of length L = 71 mm supports a load of P = 4.1 N at its center and has a web thickness of b = 2.1 mm.
