1. A bar with uniform cross-sectional area. A, elastic modulus, E, and length, L is loaded with distributed loads g(x). The bar is fixed on the right end and attach to the spring of stiffness, K. which is relaxed when the bar is undeformed. Here, Cross-sectional area. A = .05 m2, the Young's modulus, E = 210 GPa, K = 1500 kN/m. Spring constant K (x) F(spring) Cross sectional Area: Alm?) L (m) Governing equation for 1-D bar is as follows: du AE J2 = -9(x); 0
