The motor in this video was built for a project of a group of college students and it aims to introduce the working principle of magnet motor. It was built by improvisation independently from a project or drawing and completely with regard to magnet motor theory.

AISC and inelastic design

AISC and inelastic design

I'm having a rough time understanding the ramifications of AISC's use of inelastic design in the 13th edition of the steel construction manual.

It appears that AISC's use of the plastic section modulus to solve for the Allowable Strength of a member will allow members to be stressed into the plastic region, which would cause permanent deformation. Does this mean that loads which do not exceed that allowable strength have the potential to permanently deform the member?

For example, say you have a flag pole subject to repeated lateral loads, isn't it possible that the pole could be bent over by loads that do not exceed the allowable strength?

Is this covered in an appendix somewhere?

Random idea.

Random idea.

The x-seed 4000 is the tallest possible building, so if you was to get round the legal and getting there issue, could it be built today (obviously not like, now, but started now and finished in the future) out of pykrete in an ICF style fashion, possibly a nuclear reactor in the basement to power the super freezer running throughout the walls?

Can I get some advice? I’ve worked with steam plant and equipment for the last 10 years anything to 30 bar steam boilers. Got a job opportunity where the steam boilers are rated to 100 bar and to I’m a little afraid. Can someone explain to me why this higher pressure is no more dangerous.

Is there any Atex subreddits i’m missing out on?

Is there any Atex subreddits i’m missing out on?

Hello – I work for a company who specialize in Ex proof lighting for gas/dust hazards, and I'm looking for suggestions on related subreddits I'm missing out on?

I'm new to the industry so looking to immerse myself in reddit info. TIA
