A rectangular piece of wood, 250 mm by 700 mm in cross section, is used as a compression block shown below. Determine the axial force P that can be safely applied to the block if the compressive stress in wood is limited to 15 MN/m2 and the shearing stress parallel to the grain is limited to 25MN/m². The grain makes an angle of 30° with the horizontal, as shown.
