# Combined Stresses

## Problem 920 | Additional Centroidal Load to Eliminate Tensile Stress Anywhere Over the Cross Section

**Problem 920**

A compressive load *P* = 100 kN is applied, as shown in Fig. 9-8a, at a point 70 mm to the left and 30 mm above the centroid of a rectangular section for which *h* = 300 mm and *b* = 250 mm. What additional load, acting normal to the cross section at its centroid, will eliminate tensile stress anywhere over the cross section?

## Problem 918 | Stress at Each Corner of Eccentrically Loaded Rectangular Section

**Problem 918**

A compressive load *P* = 12 kips is applied, as in Fig. 9-8a, at a point 1 in. to the right and 2 in. above the centroid of a rectangular section for which *h* = 10 in. and *b* = 6 in. Compute the stress at each corner and the location of the neutral axis. Illustrate the answers with a sketch.
