A rigid horizontal bar AB hinged at A is supported by a 1.2 m long steel rod and a 2.4 m long bronze rod both rigidly fixed at the upper ends as shown in Fig. below. A load of 48 kN is applied at a point that is 3.2 m from the hinge point A. The areas of cross section of the steel and bronze are 850 mm? and 650 mm respectively. Find i) The stress in each rod ii) The reaction at the pivot point E= 205 GPa and Es=82 GPa (Ans: Stresses in steel and bronze rods are 57.04 and 95.04 MPa respectively and Pivot reaction: 69.8 kN ) |-0.8m-1:6 m- 0.8m- B 48 kN STEELA BRONZE 2.4 m
