A steel plate 5/16" thick is embedded in a horizontal concrete slab and is used to anchor a high-strength cable as shown. The diameter of the hole in the plate is 3/4", the ultimate strength of the steel used is 36 ksi, and the ultimate bonding stress between plate and concrete is 300 psi. Knowing that a factor of safety of 3.6 is desired when P = 2.5 kips, determine; The required width a of the plate (assume an average stress distribution across the reduced cross-section through the 3/4" hole), the minimum depth b to which a plate of that width should be embedded in the concrete slab. (Neglect the normal stresses between the concrete and the bottom edge of the plate.)
