3. For a built-up double angle 2L203x102x22 section with a back-to-back spacing S of 10 mm, compute the area (A), moment of inertia about X-X axis (I), elastic sectional modulus about X-X axis (S,), radius of gyration about both axes (x, y). Then compare the values with those given in the Steel Handbook (Pages 5&6) and discuss the difference between the Handbook values and your calculations. Identify the minor and major axes of the section. The yield strength is equal to F = 350 MPa. S
