Problem 1 (20 points) (Please present the graph of deflection, and a table of first 5 iterations for using the golden-section method, along with you Matlab file) 7.20The deflection of a uniform beam subiect to a linearly increasing distributed load can be computed as 2 ,.3 120EIL Given that L 600 cm, E- 50,000 kN/cm2,130,000 cm4 and wo - 2.5 kN/cm, determine the point of maximum de- flection (a) graphically, (b) using the golden-section search until the approximate error falls below S-1% with initial guesses of x,-0 and Xu = L
