Question A trampoline can be modeled as indicated in the figure. A) Determine the diagrams of V and M, as well as the minimum cant that should be placed on the 40 cm wide piece of wood if You want the maximum bending stress not to exceed 15 N/mm². Suppose the weight of the person is 800N, neglect the weight of the piece and the impact factor. B) What else? important aspect, apart from the established assumptions, is not considered in this problem and What should be checked in professional practice when designing the part? C) If I had the choice of design the part with common aluminum or with mild steel, which would you prefer and why? Sección Transversal Peralte Ancho 1.2 m 0.8 m
