I'm doing Science(Physics) & Computer Engineering double degree. I love my coding class, but I have the following issues with engineering, maths and physics: Ever since I began studying science (and discovered by greatest talent and passion) I always get told by my colleagues that I go 'too deep', and on compliments that i am 'extremely logical'. Basically, I always stick with things and explore a new concept until I can simplify it to it's fundamental truths and logically see how/why it really is the way it is. eg1, drew the geometry and derived the formula we needed when using an apparatus to get the radius of a loop today, before i plugged in numbers eg2, spent all day thinking about and drawing thought experiments of the general theory of relativity until i saw the logic behind it all, instead of remembering facts. I really dislike how in the engineering and maths subjects we are taught 'rules' to remember and use. This is fine, is you're an engineer who just wants the tools to use to problem solve. i want to derive and make tools, and manipulate existing tools with a deep understanding. i hope that's enough description of what I want. What degree/area should I look into for this??

Best answer: We see the videos. We draw our own conclusions.
Not speaking about Grenfell tower, but another concrete tower in Las Vegas that burned in the upper stories for 2 weeks. Building is still standing.

The Trade Centre towers were built to EXCEED the building standards...in earth quake, in high winds, and even if an airplane hit the thing. All were factored into the calculations. It had an abundance of redundancy built into it. The building was noted to be built of steel pillars and window glass was in combination for its strength.

Jet fuel burns at 800F It is a cold burn. It needs pure oxygen to burn hotter. It smoked...meaning lack of oxygen...and burning colder as it burned wood desks and fabric.

Jet fuel is not some magical fuel. It is diesel/or kerosene. Extra refined but very similar to the fuel for diesel vehicles or kerosene lamps.

-structural steel begins to soften around 425°C and loses about half of its strength at 650°C

You will see the numbers and do the comparison
(most people do without looking at the measuring scale) Fuel burns at 800. steel softens at 650.
one is in Fahrenheit and the other in Celsius(they got tricky here)and equate the 2 temp scales as being the same. They are far from it.

So lets make it all Celsius. So we are comparing apples to apples

800F is now 427C. Now the steel is just hot metal.
Window Glass(as the structures were made of steel and glass) softens at 800C. Not all the windows broke.(800C is the low range as it could be 1000C on glass when it is starting to get soft.)
.This is the information on the web regarding the melting point of steel beams
.the melting point of window glass
.Gypsum don't melt or burn and is strong when pushed on the edges.
I am not even figuring with concrete yet. Concrete would be used on the floors...so pancakes. supported by steel beams and glass throughout the structure.
Sure, there may have been some upright concrete posts(floor to ceiling)or a concrete tube for the elevators is common would go up many floors...and around the stairwells which is why they call it a well.

The temperature is a long ways from 650C which would soften the steel to half the strength.
At even half the strength because of the amount of redundancy built into the structure, there is no way in hell that could have collapsed especially starting 3/4 of the way up...like there is nearly no weight above it. The jet became instantly just fuel on the floors. The engines from the plane have a weight which can be found on Google and that is sitting like a display of several big cars the floor. The rest of the plane weighs next to nothing...being aluminum.

So I have ruled out softening steel and softening window glass, rumbling drywall, crumbling concrete stairwells and concrete elevator shafts.

You made an error in your initial statement. Building 7 was slated for controlled demolition. It had explosives placed where they needed to be placed so it would fall into its own foot print. You can see the rate of fall of a controlled demo. and compare it to Tower 1&2. It is the same.
. The plane striking the building did not cause the building to tilt over. It was like a bug hitting the windshield of the car or just did a "SPLAT".

Amazingly the week before the owners of the building got a multibillion dollar insurance policy on both buildings specifically in case an aircraft hits it and the buildings go tumbling down. "Like they did" so the owners collected the insurance money.

The Towers were in financial hardship at the time, too with many of the floors empty...so no rental money.

When you do the arithmetic you can see this was an inside job...not some goat herders who could not fly a Piper Cub let alone a Jumbo Jet and do some flying that all trained pilots cannot do, then the question of whether it was a plane that hit the building or a missile.

So many questions and no answers as the government cleaned up the mess and shipped it all away to be reprocessed overseas. All the evidence is gone.

Much went on that was not normal procedure.

But right away, FOX news was claiming who done it...even before the White house had a report.

It was a government scam.
I look at the FACTS without emotions getting in the way.

• ### What happens if you put a 120 volts on the wrong side of a bell transformer.?

Best answer: The secondary inductance is too low to prevent core saturation, ie it will "short" the 120VAC which will snap the power service breaker and/or heat the transformer into flame in a couple seconds. Bell transformers have no diodes or capacitors.

If you're an American, each state governs the licensing of engineers, and each has slightly different rules and requirements. Many states grant you 1 year of credit towards the experience required to sit for the PE exam if you obtain an MS degree in an engineering field.
