1-D Strong Form For a given 1-D rod, the specified distributed body force is described by: b(x) = b_0 astir (a) x/L. Determine u(x) if both sides of the rod are fixed Determine u(x) if the rod is fixed at u 0 and free at u = L Given the following: E = 20,000ksi, A = 10in^2, L 20in, b_0 = 10 lb/in, in plot your calculated displacement function for part b in MATLAB Calculate and plot the stress distribution for part b Tapered Rod For a tapered rod (A(x) is not constant), solving the strong form equation is harder, but still possible. For a 1-D rod with fixed end conditions, a constant distributed body force, b(x) = b_0 = 5 lb/in, and a cross-sectional area defined as A(z) = 5 +2x, the solution for the displaced shape looks like: u(x) = -1/E (1/4C_1 ln (2x+5)+C_2-5x/2) Determine u(x) if both sides of the rod are fixed (u(0) = 0, u(L) = 0) Given the following: E = 20,000ksi, A = 10in^2, L = 20in, b_0 = 5 lb/in, plot your calculated in displacement function in MATLAB Now approximate the solution using matrix/direct stiffness methods. Break the rod into several elements of varying areas and lump the distributed forces as point loads at the nodes.
