Problem 1.50 Determine the factor of safety for the cable anchor in Prob. 1.49 when P = 2.5 kips, knowing that a = 2 in. and b = 6 in. Problem 1.49 A steel plate 14 in. thick is embedded in a concrete wall to anchor a high-strength cable as shown. The diameter of the hole in the plate is 34 in., the ultimate strength of the steel used is 36 ksi and the ultimate bonding stress between plate and concrete is 300 psi. Know¬ing that a factor of safety of 3.60 is desired when P = 2.5 kips, determine (a) the required width a of the plate, (b) 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 end of the plate.)
