• ### 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

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...

• ### 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...
