Unformatted text preview: **Please turn over for problems 3 and 4** 3. A steel truss loaded as shown is supported by a pin at A and a roller at B. Determine the least weight section for member BD using one of the wide-flanged sections listed on the attached page. Assume a yield stress of 400 MPa, a load factor of 2.1 and E = 200x10 3 MPa. Lateral support is provided at each joint. 4. Determine the reactions at the beam supports for the given loading conditions....
