Question:

A supporting beam for a furnace exhaust tube made from an aluminium alloy fails in a short time.?

In order to improve corrosion resistance and strength, a beam supporting the exhaust tube from annealing furnace was mae from an age hardened aluminium alloyIn a short time the beam started to bend and failure occurredExplain the cause of the failure and advise a better solution.

Answer:

Well the best I can answer this mate is by why the have machine guns on them todayNot for aircraft but for Protection against other boats on a much smaller scale Plus if a standoff occurred against 2 ships it would sure help if you could knock of a few extra man on board however im dont know what the ranges of their weapons were at that timeIm tipping not that goodIt would also act as a good deterrent against any ship or smaller boat and even pirates from commondeering itHope this helps
I've never seen a photo of a battleship of this era with machineguns on it, so this is pretty surprisingOn boats, it make sense - these are often used to send detachments ashoreOn gun turrets, they could be used for ranging - firing tracerOtherwise they could be used for defence against torpedo attacks, although they wouldn't be very good for the job - compared with the 2 -12 pounder tertiary armament most carried for this purposeBalloons would be another possible target - it was thought that these might be used for spotting and directing gunfireThey may also have been intended for on-shore support - remembering that this was a period of colonial fightingEdit: I've just checked in my Janes Fighting Ships of WWI, and while most of the pre-dreadnought battleships are listed as having two machine guns, and several had four, only one class I've found had more than 4 MGs (Kaiser Frederich III - 8 MGs).
You should be considering something fabricated from stainless steel or InconelAluminum just will not take the temperatureAlso if there is any cycling of the temperatures then the aluminum can work harden.
They were used as defense and as a projection of power and domination I didn't know thatMilitary has no logicWhy do we have Billion $ aircraft carriers, when they where obsolete since WW2? -Aircraft Carriers are obsolete? Where have you been? Carriers are the most effective conventional weapon we haveAt least 1 CVN Battle Group has been used in over 80% of the conflicts we have responded toIt can operate underway almost indefinitely, it does need a host country or anyone's permission to operate, and it can operate on over 70% of the Earth's surface, and can strike almost anywhere in the worldEven old former President Bill Clinton said, When word of crisis breaks out in Washington, it's no accident the first question that comes to everyone's lips is; where is the nearest carrier?
Gunboat diplomacy is one answerYou only want the enemy to submit not be destroyedThe other reason is boardersBy the way, you'll be surprised at what a bunch of machine guns concentrating their fire can doLook up the battle of Leyete Gulferewhon gets a bad mark because Bill Clinton never had the awareness to say that remarkIt was said before I got in the navy in 1977.
