A polymer tee beam has cross-sectional dimensions a = 2.1 mm, b = 7.7 mm, c = 2.5 mm, and d = 3.4 mm. The vertical distance from the bottom of the beam to the centroid is 5.6072 mm. Determine the moment of inertia around a horizontal axis located at the centroid.

A polymer tee beam of length L = 75 mm supports a load of P = 3.4 N at its center and has a web thickness of b = 1.7 mm. The vertical distance from the bottom of the beam to the centroid is c = 5.8000 mm. The moment of inertia around a horizontal axis located at the centroid is 203.29 mm4. Determine the horizontal shear stress at H, which is located a = 3.4 mm above the bottom of the beam.

A polymer beam of length L = 78 mm supports a load of P = 3.7 N at its center. The beam has cross-sectional dimensions b = 2.2 mm and h = 7.8 mm. Determine the value of Q that would be used to calculate the maximum horizontal shear stress.

Load P = 2.0 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 0.30 in. and a length of L = 5.1 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 46-N eagle sits on a tee-shaped post that has a diameter of 49 mm. Determine the magnitude of the largest normal stress in the vertical part of the post. Let a = 0.45 m be the distance from the eagle to the centroid of the post.

Two bars have the same width. Which one has a smaller moment of inertia around its horizontal centroidal axis?

A polymer tee beam of length L = 70 mm supports a load of P = 4.3 N at its center and has a web thickness of b = 2.1 mm. The vertical distance from the bottom of the beam to the centroid is c = 5.2858 mm. The moment of inertia around a horizontal axis located at the centroid is 194.76 mm4. Determine the horizontal shear stress at H, which is located a = 3.5 mm above the bottom of the beam.

Load P = 17.0 lb is produced at the tip of a Regal Tip Elite 7B drumstick as a percussionist strikes a drumhead. The hickory shaft has a diameter of 0.58 in. and a length of L = 9.7 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 10.1 N. The outside diameter of the hollow beam is 72 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.

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.
