A beam is made from 6 boards that are the same size and glued together. Where does the largest horizontal shear stress occur in the glue?

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. The vertical distance from the bottom of the beam to the centroid is c = 4.5589 mm. The moment of inertia around a horizontal axis located at the centroid is 123.38 mm4. Determine the horizontal shear stress at H, which is located a = 3.4 mm above the bottom of the beam.

A polymer tee beam of length L = 73 mm supports a load of P = 2.6 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 = 5.0065 mm. The moment of inertia around a horizontal axis located at the centroid is 155.68 mm4. Determine the horizontal shear stress at H, which is located a = 3.3 mm above the bottom of the beam.

The term Iz in the formula τ = VQ/Izt is the moment of inertia of the _______ about the z centroidal axis.

A nurse is caring for an infant who has congenital heart disease. Which of the following actions should the nurse take? For each nursing action, click to specify if the action is indicated or contraindicated for the client. Medical History Infant has been feeding poorly and has had difficulty gaining weight. Admitted for feeding support and management. Infant has Tetralogy of Fallot. Nurses’ Notes 1400:Infant resting in guardian’s arms. Infant is pale, skin is warm and dry, and respirations are unlabored while at rest. Infant became tachypneic and fatigued quickly during feeding. 1500:Infant became agitated during peripheral blood draw. Generalized profound cyanosis observed. Skin cool to touch. Tachypneic with nasal flaring and intercostal retractions noted. Answer 1: Place the infant in a knee-chest position. Answer 2: Perform nasopharyngeal suctioning for a maximum of 5 seconds. Answer 3: Provide 100% oxygen by face mask. Answer 4: Prepare to assist with insertion of a chest tube.

A polymer beam of length L = 74 mm supports a load of P = 3.8 N at its center. The beam has cross-sectional dimensions b = 2.4 mm and h = 8.3 mm. Determine the magnitude of the maximum horizontal shear stress.
