Extracted text: 8.15 The force P acting on the concrete column has an eccentricity e. Because concrete is weak in tension, it is desirable to have all parts of the column in com- pression. Determine the largest value of e for which there is no tensile stress any- where in the column. (The area that is the locus of points through which P can act without causing tensile stress is called the kern of the cross section.)
