Problem 13.9 As illustrated in Fig. 13.43, consider a structure including the horizontal beam AB hinged to the wall at point A and supported by steel bar at point B. The length of the beam is l = 3.7 m and its weight is W = 450 N. The length of the steel bar is h = 2.5 m and its radius is r = 1.2 cm. If the elastic modulus of the steel bar is E = 200 GPa, determine: A (a) The magnitude of reaction force, RA, at point A (b) The tensile stress, o, exerted by the beam on the steel bar (c) The lensile strain, e, developed in the bar Tig 13 4a Probleu 139
