For the n-stringers section in the following figure, under loading conditions Vz = 7500 N and Mz 50 kNm (positif). a. Calculate the stress distribution, i.e., normal stress at the boom and shear stress at all skin section b. Calculate the twist angle per unit length and the shear centre position C. Calculate as in question (a), If the number of stringers are increased and distributed equally (stringer distance and stringer area) into 5 stringers (upper panel) and 5 stringers (lower panel) but keeping the total area of the stringers the same as in initial configuration (no mass increase). The skin and spars thickness are kept the same. d. Compare the result (c) and (a) and explain your analysis of the results 400 mm 200 mm 2 mm 6 200 mm 500 mm 1 mm 200 mm V = 7500 N 500 mm 1 mm 400 mm 3 4 mm 1 mm 1 mm 4 200 mm 400 mm For the n-stringers section in the following figure, under loading conditions Vz = 7500 N and Mz 50 kNm (positif). a.
