1 Computer-Aided Engineering Design HomeworkAssignment 1Due on September 12
2 AssignmentProblem 1Solve example 1 using (1) two elements and (2) eight elements. Compare your results to the exact valuesNote:The results form exact displacementY=0Y=2.5Y=5.0Y=7.5Y=10
3 Problem 1 (cont.)w1(Determining how much the bar will deflect at various point along its length when it is subjected to the load P)LyE=10.4x106 lb/in2, w1=2 in, w2=1 in, t=0.125 in, L=10 in, P=1000 lb.W2P
4 AssignmentProblem 2A concrete table column-support with the profile show in the accompanying figure is to carry a load of approximately 500 lb. Using the direct method discussed in class, determine the deflection and average normal stresses along the column. Divide the column into five elements (E=3.27 x 103 ksi)500 lbThe thickness of table: 3 in.9 in28 in4 in1 ft
