The internal shear force V at a certain section of an aluminum beam is 48 kN. The beam’s centroid is located 54.40 mm above the bottom surface of the beam, and the moment of inertia is Iz = 398,300 mm4. Determine the shear stress at point H, which is located 30 mm above the bottom surface of the beam.

The magnitude of Q for a hollow circular cross section will be _______ the magnitude of Q for a solid circular cross section with the same outside diameter.

A concentrated load of P = 35 kN is applied to the upper end of a 2-m-long pipe as shown. The outside diameter of the pipe is D = 330 mm and the inside diameter is d = 300 mm. Determine the magnitude of the maximum vertical shear stress in the pipe.

Loads P = 862 N and Q = 401 N act on an oak beam. Determine the magnitude of the largest shear force (consider both positive and negative values) in the beam. Let a = 0.6 m and b = 1.1 m.

Two bars have the same moment of inertia around their horizontal centroidal axes. The hollow bar has an outside diameter of 2.300 in. and a wall thickness of 0.460 in. Determine the diameter of the solid bar.

For a beam with the cross-section shown (w = 12.0 in. and h = 18.5 in.), find the distance from the bottom surface of the beam to the centroid.

Two cylindrical beams each support a shear force of 11.3 N. The outside diameter of the hollow beam is 50 mm, and its wall thickness is 3 mm. Determine the diameter of the solid beam that would create the same value of Q in both beams.

A 14-ft-long simply supported timber beam carries a P = 19.5-kip concentrated load at midspan as shown. The cross-sectional dimensions of the timber are also shown. At section a-a, determine the magnitude of the shear stress in the beam at point H.

The internal shear force V at a certain section of a steel beam is 80 kN, and the moment of inertia is 64,867,500 mm4. Determine the horizontal shear stress at point H, which is located L = 52 mm below the centroid.

The internal shear force V at a certain section of an aluminum beam is 15 kN. The beam’s centroid is located 54.40 mm above the bottom surface of the beam, and the moment of inertia is Iz = 398,300 mm4. Determine the shear stress at point H, which is located 30 mm above the bottom surface of the beam.
