A polymer tee beam of length L = 76 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 = 5.0202 mm. The moment of inertia around a horizontal axis located at the centroid is 163.47 mm4. Determine the horizontal shear stress at H, which is located a = 2.9 mm above the bottom of the beam.
