2
Assignment Problem 1 Solve example 1 using (1) two elements and (2) eight elements. Compare your results to the exact values Note: The results form exact displacement Y=0 Y=2.5 Y=5.0 Y=7.5 Y=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) L y E=10.4x106 lb/in2, w1=2 in, w2=1 in, t=0.125 in, L=10 in, P=1000 lb. W2 P

4
Assignment Problem 2 A 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 lb The thickness of table: 3 in. 9 in 28 in 4 in 1 ft
