Mech. Tech geek post.
This little book is a gem. It has all sorts of info. Thread specs, joist spans, clamping force of fasteners. Gas laws & constants. All types of electric motor specs, airport codes, ice thickness weight capacity. Resister codes Mineral tables.
Yes all this stuff is online, but this is a book and requires no battery, nor internet.
It's under $15 usd #robust#tech#SHTF#offline
