Two cylindrical beams each support a shear force of 14.5 N. The outside diameter of the hollow beam is 42 mm, and its wall thickness is 5 mm. Determine the diameter of the solid beam that would create the same maximum horizontal shear stress in both beams.

A polymer beam of length L = 79 mm supports a load of P = 4.7 N at its center. The beam has cross-sectional dimensions b = 2.6 mm and h = 8.1 mm. Determine the value of Q that would be used to calculate the maximum horizontal shear stress.

Load P = 19.9 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 0.56 in. and a length of L = 10.1 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.

A polymer tee beam has cross-sectional dimensions a = 1.8 mm, b = 7.2 mm, c = 2.0 mm, and d = 3.1 mm. Determine the vertical distance from the bottom of the beam to the centroid.

A polymer tee beam has cross-sectional dimensions a = 1.7 mm, b = 8.0 mm, c = 2.4 mm, and d = 3.0 mm. The vertical distance from the bottom of the beam to the centroid is 5.8000 mm. Determine the moment of inertia around a horizontal axis located at the centroid.

A polymer tee beam has cross-sectional dimensions a = 2.1 mm, b = 7.6 mm, c = 2.5 mm, and d = 3.4 mm. Determine the vertical distance from the bottom of the beam to the centroid.

A polymer beam of length L = 74 mm supports a load of P = 3.1 N at its center. The beam has cross-sectional dimensions b = 2.0 mm and h = 8.8 mm. Determine the magnitude of the horizontal shear stress at H, which is located a = 1.8 mm from the top.

A polymer beam of length L = 75 mm supports a load of P = 5.0 N at its center. The beam has cross-sectional dimensions b = 2.7 mm and h = 7.8 mm. Determine the magnitude of the horizontal shear stress at H, which is located a = 1.6 mm from the top.

Load P = 3.1 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 0.53 in. and a length of L = 10.8 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.

A polymer beam of length L = 70 mm supports a load of P = 3.0 N at its center. The beam has cross-sectional dimensions b = 3.0 mm and h = 8.4 mm. Determine the magnitude of the horizontal shear stress at H, which is located a = 1.7 mm from the top.
