He is on some high fiber wet food and on meneral oil is there anything else I can do?
No, it's unlikely that global warming had anything to do with itStructural Deficiency is actually a pretty good statement of the cause, as the NTSB sees it in their preliminary examinationStructural deficiency is a scale (0-100) used to rate bridges and other structuresIt combines two factors: issues or flaws in the original design, and damage, wear or weathering of the materialsThis bridge had a structural deficiency rating of 50It was in the 47th year of a 50 year design lifetimeIn the USA, it was an average bridge They will be examining the original design for we wouldn't do it that way today type issues, but most of that should already be known and included in it's ratingThey'll also look at the past inspections, as a record of how it was aging and being maintainedSome cracks for example, would be expected over timeIf and how they were dealt with alters the ratingThey are also looking at the weather on a day by day basis since the last inspectionWeather has known effects in terms of expansion and contraction, etcAll this data together should give them a pretty good idea about whether the structural deficiency rating had changed since the last inspectionBecause they have video tape of the collapse as it occurred, they already know where the first failure occurred, and how it progressed from thereI'm sure they'll be focusing on the key pointsI heard a report that it may have had more weight than normal on it at the time, due to the construction equipment doing some repavingThey'll have a pretty clear picture once all that data is put togetherI know the usual suspects on here were hee-hawing away when it happened, suggesting people would attribute it to global warmingMy heart goes out to anyone in that community reading those postsIt shows their social skills are on par with their scienceI haven't heard anyone other than those folks try to bring Global Warming into that tragedyIf some turn up, I'm sure it will be sources on the same level as our pet contrarians.
DO NOT GIVE YOUR PUPPY MINERAL OILThe 'high fiber' wet food is good, but not necessaryJust watch your puppy for a week, and if he gets 'constipated' the bone may be blocking his colon, and you will need to take him to a vet to have it surgically removedThe 'mineral oil' will kill your puppy very quickly .
No, The problem resulted from ignoring that any building or structure requires maintenanceIt doesn't matter if it's a bridge or a houseIgnore it it and it will fail in due timeThe people we elect would rather have big new bright shinny pet projects than to focus on the less glamorous things like bridge or building repairIt's not a money issue just where they place their priorities.
It is a minor contributing factorMayby 0.001% (so really nothing) Bigger contributing factors are for example acid pollutions which increase the metal corrosion, especially in steel reinforced concreteThe design of such bridges uses generally a safety factor of 4 meaning that the bridge could in theory handle a load that is 4 times what the maximum it will have to face will be (static+dynamic load) The main problem is probably that older materials and design were not built to last since there was no long term experienceMoreover no computer simulations made the design themselves vulnerable to miscalculationThis does not happen anymore nowadays using finished-elements-method to simulate.
Imo, the bridge collapse was due to the work being doneSomehow the construction weakened the structure in the work area enough to put more stress on the rest of the structure, thus causing the the bridge to collapseImo, Global Warming had nothing to do with the bridge collapse.
