Extracted text: Members A and B are made of wood and have a thickness t = 6 mm. If member B is subjected to a compressive force of 8 kN. What is, to the nearest mm, the smallest dimension h of the horizontal segment so that it does not fail in shear? The allowable shear stress for the segment is Tallow = 3.1 MPa. B F 13 12 Ih
