1. The problem statement, all variables and given/known data Two beams of different cross sectional areas are fused together to create a single beam, as shown in the figure above. The following relationships apply: A1 = 2A2, L2 = 2L1, E1 = 3E2. A tensile force F is applied at the ends of the bar, as shown. What is the ratio of the stress in beam 1, σ1, to the stress in beam 2, σ2? 2. Relevant equations stress = σ = F/A0 strain = ε = ΔL/L0 σ = Eε 3. The attempt at a solution σ1 = F/A1 = F/(2A2) σ2 = F/A2 σ1/σ2 = 1/2 I think that my answer is probably wrong because I don't think that the force being applied to the beam should just be equal to F. Is the force at the location of fusion different from F that's being applied at both ends? How would I go about calculating this force? Would this make the F in the formula for stress an average of F and the stress at the fusion point?
