고체역학 (Beer) — Introduction—Concept of Stress: Problem 1.50

1.50 Determine the factor of safety for the cable anchor in Prob. 1.49 when \(P = 2.5 \text{ kips}\), knowing that \(a = 2 \text{ in.}\) and \(b = 6 \text{ in.}\) (From Prob 1.49: A steel plate \(1/4 \text{ in.}\) thick is embedded in a concrete wall to anchor a high-strength cable as shown. The diameter of the hole in the plate is \(3/4 \text{ in.}\), the ultimate strength of the steel used is \(36 \text{ ksi}\) and the ultimate bonding stress between plate and concrete is \(300 \text{ psi}\). Neglect the normal stresses between the concrete and the end of the plate.)
