A load of P = 91 kN is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 115 GPa] rods, and a solid steel [E = 206 GPa] rod, as shown. The bronze rods (1) each have a diameter of 19 mm and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 25 mm. All bars are unstressed before the load P is applied; however, there is a 2.3-mm clearance in the bolted connection at B. Assume L₁ = 3.4 m and L2 = 1.3 m. Determine: (a) the normal stresses in the bronze and steel rods (01,02). (b) the downward deflection v of rigid bar ABC. (1) Answers: (a) σ₁ = (b) v = L₂ i 159.6 0.256 (2) B P (1) L₁ MPa, 6₂ = mm. i 185.5 MPa.
