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 approximate deflection at mid-span.
The correct answer is 26mm. The truss can be approximated to a beam. The second moment of Area of the 'beam' can bedetermined using parallel axis theorem allowing standard beam deflection equations applied for an approximate answer.
The continuous two span footbridge has a uniform EI (100,000kNm^2) and carries a total load of 12kN/m over its entire length Following a recent flood both the left hand (A) and inner support (B) sink by 25mm. Using any method determine the moment...
3-D Bending moment and torsion diagrams are never easy, so practice makes perfect. Having sketched the bending moment and torsion diagram for the structure above determine the moments and torsion acting on the base of the structure Submit your...
You are sitting in a rowing boat in a small pond, you have an unopened can of baked beans with you. If you throw the can (which sinks) into the pond what happens to the level of the water in...
