A steel plate 1 4 in. thick is embedded in a concrete wall
Chapter 1, Problem 1.49(choose chapter or problem)
A steel plate \(\frac{1}{4} \mathrm{in} .\) thick is embedded in a concrete wall to anchor a high-strength cable as shown. The diameter of the hole in the plate is \(\frac{3}{4} \text { in. }\), 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 3.60 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.)

A steel plate \(\frac{1}{4} \mathrm{in} .\) thick is embedded in a concrete wall to anchor a high-strength cable as shown. The diameter of the hole in the plate is \(\frac{3}{4} \text { in. }\), the ultimate strength of the steel used is 36 ksi. and the ultimate bonding stress between plate and concrete is 300 psi.

(Neglect the normal stresses between the concrete and the end of the plate.)
ANSWER:
Step 1 of 7
First we have to determine the required width of the steel plate for the given load, factor of safety and tensile stress, we also have to determine the minimum depth to which the plate should be embedded in the concrete based on the given bonding stress between steel and concrete.
