Problem 2: The large Red Brass C83400 copper alloy bar with cross section of (50 cmx40 cm) is suspended using the thin short stainless 304 steel wire shown. Using a factor of safety of 2, determine the minimum wire diameter needed. Also determine the normal stress (as a function of x) at each cross section within the Red Brass C83400 copper alloy bar and plot it. Hint: The bar is large and its weight must be modelled as distributed load. However, the wire is short and thin, so ignore its weight and no distributed model is needed for it
