Constructing the Hoover Dam

When it was originally built, the Hoover Dam was the largest concrete structure in the world. It weighs 6.6 million tons and stands 700 ft tall. The biggest challenge engineers faced while building the dam was the extreme heat.

As a mathematician, I couldn't help but laugh out loud at the random equations and math drawings that they threw around at 2:05

So incredible.. I loved that guys enthusiasm !

[bharatikoyale]

It freshened my memories of gta San Andreas misson of airstrip

[juangomez]

DAT DAM HAS THE SWEAT AND LABOR WORK OF MANY INMIGRANTS WORKERS....MEXICANS AND CHINESE....!!!
THEY ARE THE TRUTH HEROES IN THIS STRUCTURE AND CHALLENGE OF ENGINEERING.

It gives one a clue at how good of a work ethic the men who built the damn had. It takes five years for people today to built a new bridge for an interstate overpass.

Nah they just told the water to stop lol

[WalterIngalls]

Ya know what a ferrite bead is?

I'd like to add an electromagnetically charged coil to the top of the dam so that it draws metals from the water (and some fish have metallic scales that they get from eating metallic elements in algae)

I feel like an idiot for thinking this was a fallout new vegas video 😂

[ScoutJoe]

was hoping to see some NCR rangers patrolling around it

Who’s here after the tik tok wondering how dams are built

[nicknack]

Don't let you distract you from the fact that Lightning McQueen blew a tire on the final lap of the Piston Cup!

[nickthepark]

I just have one question. Is this a God Damn?

[mukkasaurus]

Well we can take the dam down now. Lake Mead is about dried up.

[Oppathicc]

About construct in a dam.
Comments about politics.
yes.
okay.

[briancaster]

Does anyone else think he sounds like Dan Ackroyd?

[johns.]

@0:30 - Look at how low that water level is? That lake is almost dry.

[internetclown]

135 years for concrete to cure? The Great Depression would be long gone by the time the dam is complete. It'd take 400 years to build the dam.

[TrekIsKute]

I've been inside the Hoover damn they stopped doing those tours tho

[KidZeppelin]

Could the ancient Egyptians have done this? Lol

I AM ALSO COMMENTING FROM A HELICOPTER FOR NO LOGICAL REASON, EXCEPT TO GIVE MY COMMENT A SENSE OF IT WORKS! OK LET'S FLY BACK DOWN TO THE GROUND NOW I'VE HAD ENOUGH EXCITEMENT FOR ONE DAY.
