1. A steel plate 5 /16 in. thick is embedded in a horizontal concrete slab and is used to anchor a high- strength vertical cable as shown. The diameter of the hole in the plate is 3 /4 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 bottom edge of the plate.

1. A steel plate 5 /16 in. thick is embedded in a horizontal concrete slab and is used to anchor a high-
strength vertical cable as shown. The diameter of the hole in the plate is 3 /4 in., the ultỉmate 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 bottom edge of the plate.
