Photoelasticity- how engineers “saw” stress in the 70’s
Photoelasticity (often called photostress) was the go-to way to “see” stress in transparent parts from about the 1940s to the 1980s. Engineers coated or made models from special plastics, then viewed them under polarized light—stress showed up as colorful fringe patterns, making high-stress areas easy to spot.
Before that, stress was measured with mechanical strain gauges or calculated by hand. Today, it’s mostly replaced by digital strain gauges and finite element analysis (FEA), which give faster, more precise results without physical models.
@MarioNawfal At a high enough velocity, anything can fly. Our atmospheric density makes it easy to a certain point. A 747 wont fly on Mars but if you could speed it up to mach 3 it might.
@elonmusk@ENERGY@SecretaryWright How about drilling 10-12 km deep into the earths crust and using geothermal heat to create energy. The sun sets. This will have a constant base load , zero emissions, small foot print and high capacity factor. Drilling that deep is difficult, but you’re not into the easy things.
@adskFusion how is anyone supposed to use your software when it’s this slow. I have 3 licenses and it’s bloody useless. Especially when you need to use it for production.
@Lesufi Explain to me….. why do we use such thick cables to power 3 light bulbs? You might as well put a gold bar inside each light post. Step that down to 220v and use thinner cables to power LED lights. It won’t be worth stealing. Message me and I will make you a concept.
