Question 24
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...

Question 23
3D 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...

A quick question to make you think
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...
