We’re continuing our look at engineering materials with third main type of material that you’ll encounter as an engineer: polymers. They’re made of long, repeating chains of smaller molecules known as monomers and today we’ll explore their strange history of polymers and the things that contributed to how we use them today.
Crash Course Engineering is produced in association with PBS Digital Studios: • All PBS Digital Studio...

To provide more learning, I can add a mini-crash course on some polymers and plastics info.

Important piece of information about elastomers: they absolutely must be cross-linked to return to their original shape, otherwise they just deform permanently (which means they flow like a syrup, in this context)

Fun fact: Nylon, Kevlar and Teflon were all created by the same company, DuPont. They also created Nomex (a fire-resistant fabric) and Spandex.

Firemen use standpipes to fight fires in high rise. Standpipes are usually located on the stairwells. They connect and set up on the floor below the fire and then go

You can work and research polymer materials following the career of Chemical or Mechanical Engineering (first is more the chemistry and production; second is their mechanical properties).

Very important lesson. Especially since I’m back in physics and engineering is a big part of it

Once around here an ink factory was on fire it took about 10 fire trucks and three refill dosers plus the HVAC system and all the fire extinguishers that can get their hands on to put it out

Can't wait to refer to the PVC at work as a "cylindrical tube of polyvinylchloride". That'll teach those construction contractors to talk down to retail associates at home improvement stores.

We learned polymers today in class. I got confused. You uploaded a video on the same. I got even more confused. CONFUSION: 100.
