Question 9
The top and bottom chord of the long truss shown below are CHS sections, and each has I = 31x106 mm4 and A = 6300 mm2. Take Esteel = 200 GPa. All members have the same length of 1m. Determine the...

Question 8
Correct SFD is D: Check out http://expeditionworkshed.org/applets/2D_frames/sketch_10/sketch_10.html for a great pushmepullme model of the problem. Thanks to Al form supplying the answer The answer is: D Since the load is applied at an angle, there two components of that load:...

Question 6
For the structure shown below calculate the position of the roller support from the free end of the beam (C) such that the moment at the fixed end (A) is zero kNm. [Solution x=3.33m] If you didnt get it right...

Question 5
After the maths of last week's question, here is something to make your brain work in a slightly different way! UPDATE: Its about real world design and the implications of inaccuracies in construction. A person weighing 600N sits on a threelegged stool....

Question 3
Match each Shear Force Diagram (SFD red) with a Bending Moment Diagram (BMDblue). Hint: BMDs are drawn on the tension side of the deflected shape. Match each Shear Force Diagram (SFD red) with a Bending Moment Diagram (BMDblue). Hint: BMDs...

Question 2
No calculations this week! Which BMD matches the loadcase for the structure shown below ? Choose from the following What a week over 60 entries! Unfortunately only 50% of them correct ( BMD:4). Quick Explanation: As the right hand support is...
