CIV 101$  STRUCTURES, MATERIALS, AND DESIGN Examiner: Peter M. Wright NAME:
(Please print clearly and underline family name) STUDENT NUMBER: CIRCLE MODEL NUMBER OF CALCULATOR CASIO 991 SHARP 520 TI 30 NOTES: 1. Be sure you have all 7' sheets of this examination paper Page 7 is blank.
2, Answer all 5 (ﬁve) equalvalued questions.
3. No other paper will be accepted for marking nor allowed on the desk.
4. The permissible calculators are listed above. DO NOT WRITE IN THIS SPACE. H H Name Page 2 of 7 The members of the steel truss shown are rectangular hollow structural steel sections with outstdc
crosssectional dimensions ofb and 2b. and inside ones of 0.8b and 1.6b.
(3) Determine the internal actions in members GH and GE
(b) Determine the minimum value ofb for member GH. The modulus ofelasticjty E = 200 x lo’
MPa and the yield stress for the material is 380 MPa. The factor of safety (load factor} for
yielding is to be 1,8 and for buckling it is to be 2.5. H l D 0 Name _ ‘ Page 3 of? The uni fonnly—lhick plate ABC which is the lid for the triangular ccntamcr slimm has a weight of
600 N/m? 11 is supported by a cable CD, a ring at A which can not support a force in the z—
dircclion, and a ballandsockct at B. (3) Sketch the free body ofthc lid (b) Determine the tension in the cable (c) Determine the reaction componean at A. Name Page 4 of 7 3. A steel beam is fabricated from 3 W356 x 61, and a plate 10 mm x 300 mm welded together as
shown. The loading on the beam is also shown, as are the properties ofthe W356 x 64. Assuming
linearly elastic material, determine the maximum tension and compression stresses due to bending moment. W1 .. no ind /m
