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)
