Using the global assembly FEA method, generate a system ofequations for the 1D FE model shown below, and determine the axialstress in element 4 (MPa).
a) Young’s modulus of all 6 elements E = 200GPa,b) the end points of the 6 elements are:x1 = 0,x2 = 25mm,x3 = 100mm,x4 = 150mm,x5 = 175mm,c) the inner (r) and outer (R) radii of elements 1 through 6are:r1 = 0mm, R1 = 10mm;r2 = 5mm, R2 = 7mm;r3 = 0mm, R3 = 4mm;r4 = 8mm, R4 = 10mm;r5 = 0mm, R5 = 4mm;r6 = 0mm, R6 = 7mm.d) the applied displacement at node 5 is defined as Uapp =0.1mm.e) the applied force at node 2 is defined by Fapp = 100000 N.
