The internal shear force V at a certain section of an aluminum beam is 46 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 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 = 25 mm below the centroid.

Identify this connective tissue. (Do NOT type the words “connective tissue” in your answer.)  

A polymer beam of length L = 70 mm and a = 30 mm supports a load of P = 5.0 N at both ends. The beam has cross-sectional dimensions b = 2.0 mm and h = 8.9 mm. Determine the magnitude of the maximum horizontal shear stress in the beam.

Two cylindrical beams each support a shear force of 12.9 N. The outside diameter of the hollow beam is 40 mm, and its wall thickness is 5 mm. Determine the diameter of the solid beam that would create the same value of Q in both beams.

A block of mass M slides down a frictionless plane inclined at an angle θ with the horizontal. The normal reaction force exerted by the plane on the block is
