Having problems with part (c) here, question is attached below in full. 1. The problem statement, all variables and given/known data Using the equation 1/2 * Load * Displacement = Sum of (P^2 * L/2AE) From the past questions I have the following info, these are also included in the solutions so are accurate: A = 1x10^3 m^2 FAB = 90kN FBC = 120kN Length of AB = 1.5 m Length of BC = 2 m 2. Relevant equations 3. The attempt at a solution My attempt at the solution: 1/2 * 150 x 10^3 * Displacement = 1/(2 * 1x10^-3 * 205x10^9) * ((90x10^3^2 * 1.5)+ (120x10^3^2 * 2)) Displacement = ((90x10^3^2 * 1.5)+ (120x10^3^2 * 2)) / 1x10^-3 * 205x10^9 * 150x10^3 = 1.33 mm The correct answer, per the solutions, is 2.08 mm. Any idea where I've gone wrong? Thanks.
