AI Thread Summary
To calculate the bending moment diagrams for the bridge when extending and at 35 meters, one must consider the forces acting on it, including the support reactions and the weight of the bridge. The total load on the bridge includes the hydraulic pump and the bridge's mass, which must be converted to Newtons. The bending moments can be determined by applying static equilibrium equations and analyzing the moments about specific points. Additional information, such as the bridge's cross-sectional properties and the locations of the supports, is necessary for accurate calculations. The inquiry appears to be related to a homework problem, indicating a need for further clarification on the parameters involved.

The bridge is full extend 35 meters long, and retracted 17,5 meter long.
When the bridge is installed it rest on piont(375kN) and a
hydraulic pomp (525kN) , the mass of the bridge is 15 metric ton.

my question is how do I calculate the bending moment diagrams when it is extending and how do i calculate the bending when it is at 35 meters.

Is this a homework question ?
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
