H Packer, Jeffrey A. B Kuhn, Eva ' F Birkemoe, Peter C. J El-Diraby, Tamer C Richman, Russell C. G Tang, Zhong K ‘ Kuhn. Eva D Wilkinson, Tim CIRCLE MODEL NUMBER OF CALCULATOR CASIO 260 SHARP 520 TI 30 Be sure you have all 7 sheets of this examination paper. Page 7 is blank. If you need more space for a question normally you should use the back of the preceding question. In all cases indicate clearly where your calculations are continued. NOTES: 1 . Answer all 5 (five) equal-valued questions. 2 3. No other paper will be accepted for marking nor allowed on the desk. 4 The permissible calculators are listed above. 5 Solutions must include free body diagrams which are NOT to be superimposed on the original sketches. DO NOT WRITE IN THIS SPACE. Page 3 of 7 Name 2. A timber truss is loaded as shown. Determine: (a) The internal forces in members CD and GF. (b) The required cross-sectional dimensions for member CD if the timber is to be square and is only available 7 in width increments of 10 mm. Use a failure/yield stress of 25 MPa, a load factor of 2.1, and E =12 x103 MPa.. ZokN 30 4~okN Page 4 of 7 Name 3. A uniformly thick steel plate which has had a triangular hole cut out of it as shown has a mass of 200 kg. All of the dimensions in the sketch are in millimetres. It is supported by a ball-and-socket at A, two pin- connected bars at D, and a'C'able CE. Determine the tension in the cable and the forces in the two bars at D. Name Page 5 of 7 4. The pin-connected frame shown supports a weight of 2 kN. The radius of the pulle is 0.] m. (a) Determine the reaction components at A and B (h) Qimtch the, V and M riingmms for member BFF in the space provided. Page 6 of 7 Name 5. A welded built-up beam is fabricated from a 203 x 102 x 8 hollow structural section and two steel plates, 10 mm x 300 mm, as shown. The loading is also shown below. Determine the maximum compressive stress due to bending moment and indicate where it is located in the beam. Neglect the self-weight of the beam.
