21 P.17.6. Figure P.176 shows the singly symmetrical cross-section of a thin-walled open section beam of constant wall thickness I, which has a narrow longitudinal slit at the comer 15. Calculate and sketch the distribution of shear flow due to a vertical shear force S, acting through the shear center S and note the principal values. Show also that the distance Es of the shear center from the nose of the section is Es 1/2(1 + alb). Answer: 92 = 94 = 365,/2)(b + a), 43 = 35,/2h, parabolic distributions I 21 2a Es IS 175 24
