A beam with 2in by 3 in cross section is supporting 1000 pounds what is the stress on the beam

The stress is 166.66 pounds per square inch.

You might be correct, but then again you may not be. We just don't have enough information from what the OP posted to solve this problem. If the beam is acting purely as a column that is bearing a load of 1000 pounds, then yes - its cross section of 6 square inches is supporting 1000 pounds weight, for 166 PSI (assuming the beamn itself is weightless). However, we don't know if that is how its being used. If the beam is spanning between two simple supports (like a floor joist), or is cantilevered from a wall supporting a weight (like a diving board), then the stress varies with position along the length of the beam. So to answer this question we need more information, such as the length of the beam, its cross-section height and width, the point where the load is applied, and the method of support of the beam.
