A polymer tee beam of length L = 71 mm supports a load of P = 4.3 N at its center and has a web thickness of b = 1.9 mm. The vertical distance from the bottom of the beam to the centroid is c = 4.8594 mm. The moment of inertia around a horizontal axis located at the centroid is 132.06 mm4. Determine the horizontal shear stress at H, which is located a = 3.2 mm above the bottom of the beam.
