4 Assignment 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 10 3 ksi) Problem 2 9 in 1 ft 28 in 500 lb 4 in The thickness of table: 3 in.
