*How successful were you at mathematically predicting the failure of your beams design? As we calculated the force using the formula σ = (F L do)/I and the typical MOR of yellow poplar 9300 lb/in^2 according to the____ before doing the experiment, the maximum forces that the beams made yellow poplar can hold was 32.00 lb. Through the experiments, The forces we obtained were 37.88lb, 34.88lb and 24.88lb, and the average maximum force that yellow poplar beams could hold was 32.55lb that quit similar to the predicted value. As a result, the average maximum stress Modulus of Rupture (MOR) obtained by our experiment values—11007.61 lb/in^2, 10135.61 lb/in^2, and 7229.92 lb/in^2—was 9457.79 lb/in^2 (MOR = F L do/I). This is also close to the typical MOR of yellow poplar. Mathematically, we succeed in this experiment to find out the MOR.
