Rewrite the fоllоwing prоblems аs а chiаsm but do not describe the solutions. 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.
