Extracted text: Question 1 - Combined Stresses Given in figure 1, stub column with dimensions a, b and wall thickness t. Four point loads work in on the column's top surface: 14KN (on the corner as shown), 6kN (on the corner as shown), 8kN (on the side on the y-axis), 4kN (horizontal parallel with the x-axis as shown). Draw the stress distribution on a cross section situated at h from the top of the section. Also determine the equation of the line of zero stresses by transferring the xy-axis shown to the relevant h you are working at. Also provide the coordinates where this line intersect the sides of your section at your relevant h. at point 2: h = 2.5m; a = 200mm; b = 400mm; t = 15mm a 14kN 8kN 6kN 4kN m 1 2 3 p Figure 1
