Yоu аre аsked tо use the Finite Element Methоd to аnalyze the truss shown below with Fappl = 25 kN: With the following values for all three truss members: A = 500 mm2, E = 200 GPa, I = 1.67x10-8 m4, Sy = 250 MPa a.) In the matrix equation on the printed handout describing element #2 (shown here), fill in the symbols for the appropriate element forces and displacements (No values, just symbols: F# & δ#). b.) Construct the stiffness matrix for element #2 (E2 in the figure). On the printed handout, enter all 16 of the stiffness values in the matrix with the correct units of stiffness (using simplified base units: m, N, kg, s, etc.). c.) The element stiffness matrices for the other elements (k1 & k3) are given here. Using these and the element stiffness matrix, k2 (from part b.), fill in the missing numbers in the Global Stiffness Matrix of the entire truss on the printed handout (also shown below). Then, fill in the known boundary conditions by filling in the blank cells in the Force (F) and Displacement (δ) vectors. For unknown forces or displacements, fill in a question mark (?). d.) There are only two unknown displacements, δ1 & δ6, in this scenario. Using two equations from the completed matrix equation in part (c) above, calculate these two unknown displacements. Show your work on the printed handout and include units and correct signs in your answer. e.) Using the element stiffness equations, calculate the element forces acting on element #3 (include units) and draw them on the element on the printed handout. Calculate the change in length of this member, δ, and the predicted strain, ε. Determine if this member will fail in any way under this load. Show all your work for this problem on the printed handout. Note: if you did not get displacement values in part d) above, use substitute values of δ1 = -0.4 mm and δ6 = -0.09 mm. Note: you don't need to enter anything in the box below.
The shаft (OA) is mаchined frоm 1050 cоld-drаwn steel (Sy = 580 MPa, Sut = 690 MPa) tо the dimensions provided. The shaft rotates at constant speed of 2000 rpm and is supported by bearings at O and C. The belt tensions on pulleys A and B result in a constant torque on the shaft of 300 Nm and a completely reversing bending moment at critical point C of 650 Nm. The transition between diameters at point C has a fillet with a 2-mm radius. Determine the following: The modified endurance limit (Se) for this application with 90% reliability The factor of safety for first-cycle yielding (ny) The factor of safety with respect to infinite life (nf) using the Modified Goodman criteria Write down all your work to scan and submit. Se = [Se] MPa (round to 0 decimal places)ny = [ny] (round to 2 decimal places)nf = [nf] (round to 2 decimal places) LOB = 230 mm, LBC = 280 mm, LCA = 300 mm, dOB = 45 mm, dBC = 50 mm, dCA = 42 mm
