A polymer beam of length L = 70 mm supports a load of P = 2.4 N at its center. The beam has cross-sectional dimensions b = 2.7 mm and h = 8.2 mm. Determine the value of Q that would be used to calculate the maximum horizontal shear stress.

A polymer tee beam has cross-sectional dimensions a = 1.9 mm, b = 7.6 mm, c = 2.2 mm, and d = 3.2 mm. Determine the vertical distance from the bottom of the beam to the centroid.

A polymer tee beam has cross-sectional dimensions a = 2.0 mm, b = 6.5 mm, c = 2.0 mm, and d = 3.3 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 = 4.2 N at its center. The beam has cross-sectional dimensions b = 2.1 mm and h = 7.2 mm. Determine the magnitude of the horizontal shear stress at H, which is located a = 1.4 mm from the top.

A polymer tee beam of length L = 71 mm supports a load of P = 3.2 N at its center and has a web thickness of b = 2.0 mm. The vertical distance from the bottom of the beam to the centroid is c = 4.9347 mm. The moment of inertia around a horizontal axis located at the centroid is 147.03 mm4. Determine the horizontal shear stress at H, which is located a = 2.5 mm above the bottom of the beam.

Two cylindrical beams each support a shear force of 13.6 N. The outside diameter of the hollow beam is 66 mm, and its wall thickness is 3 mm. Determine the diameter of the solid beam that would create the same maximum horizontal shear stress in both beams.

Two cylindrical beams each support a shear force of 11.6 N. The outside diameter of the hollow beam is 46 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 beam of length L = 73 mm supports a load of P = 4.4 N at its center. The beam has cross-sectional dimensions b = 2.8 mm and h = 7.7 mm. Determine the magnitude of the maximum horizontal shear stress.

Load P = 11.8 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 0.55 in. and a length of L = 11.1 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.
