Problem 1.68 A force P is applied as shown to a steel reinforcing bar that has been embedded in a block of concrete. Determine the smallest length L for which the full allowable normal stress in the bar can be devel¬oped. Express the result in terms of the diameter d of the bar, the allowable normal stress ?all in the steel, and the average allowable bond stress ?all between the concrete and the cylindrical surface of the bar. (Neglect the normal stresses between the concrete and the end of the bar.)
