The final mass of the object is 398 g or 0.8782 lbs, representing an 80.6% reduction. It features a stiff hollow construction with varying wall thickness to maintain both lightness and strength in necessary areas. The creator believes that the project could be made lighter but time constraints prevented further optimization. The analysis setup includes rigid elements such as bolts, pins, and surfaces, with friction set at a coefficient of 0.4. In the analysis results, peak stresses were observed at contact surfaces in all load conditions, which the creator attributes to simplifications in the model. In reality, contact stresses should be lower. The maximum stress (2339 MPa) in load condition 2 is concentrated on a single node of a coarse element. Other results display stress levels below the yield point, indicating sufficient strength. Overall, the creator believes that the design is satisfactory but acknowledges potential improvements if more time had been available.
