Trusses Definition and 55 Threads

Homework Statement I'm currently doing a assignment about trusses, it's all about the theory, concept, animation and calculation. However, I'm lack of sources for doing this assignment. So, can anyone please kindly recommend some useful links to me? Thank you... : )

I'm doing a research paper on bridges, and I'm having trouble finding an example contrasting the magnitudes of forces on a bridge with trusses as opposed to a bridge without trusses. I understand pretty clearly how a truss works, however I need to give an example with numbers, and I'm not...

Look at the bottom problem at this page: http://physics.uwstout.edu/StatStr/statics/StatII/statp22t2.htm When I have found the force Ay (the y-component of the reaction force at point A), does that in this case mean that the force in member AE is then equal to this? If so, then the force...

http://www.unm.edu/~hr/images/test/problem.bmp I am stuck trying to see how to apply the equilibrium equations. I take the moment about point b and get Fce. I need Fbe, and Fbd. Fbd = 95.6 kip Fbe = 41.1 kip Fce = 58.4375 kip These are the answers. I don't know how they got Fbd and...

Question on equilibrium in roof trusses... The diagram for this quesion is at http://www.drewtemp.com/helios/physics.gif 1. What i want to find is which members are in tension and compression (AB, BC, AC)? 2. What is the force at AC? 3. What force from the left (the wind) is...
