cross-sectional area of A₁ = 780 mm². Bar (2) is a bronze alloy [E = 950 m, L2=2.9 m, a=0.5 m, b=1.1 m, and c-0.8 m. All bars are unstressed bet the pin connection at A. If a load of P = 41 kN is applied at B, determine (a) the normal stresses 0₁, 0₂, in both bars (1) and (2). (b) the normal strains E₁, E2, in bars (1) and (2). (c) determine the downward deflection VA of point A on the rigid bar. (1) A Answers: (a) σ₁ = (b) ₁ = (c)x₁= a i M L₁ B P b (2) C L2 mm. C MPa, 0₁ = με, €2 = i D
