The graph in Fig. 8 shows the relationship between variations in operating load and the maximum displacement and stress, with both parameters increasing linearly with load. This linear trend indicates that the structural response is proportional to the applied load, consistent with linear elastic material behavior. As shown in Fig. 9, the safety factor decreases systematically with increasing operating load due to the higher stress levels, but it remains well above unity for all load cases, confirming that the trash box operates within a safe elastic range across the tested operating conditions
