    Job Smoke
AI Thread Summary
A BBC video shows a worker weakening a tall smoke stack, raising concerns about safety. The method of weakening is preferred over explosives for its ease of cleanup and predictable fall, minimizing risks to nearby structures. This approach is also more cost-effective than a controlled demolition. Cutting down large structures has been done for centuries, and the primary danger lies in improper execution. The discussion emphasizes the balance between safety and efficiency in such demolition practices.

BBC had video clip of a worker presumably weakening a tall smoke stack. Looks somewhat dangerous. See,

Why weaken it? Why not just use explosives?
 
Engineering news on Phys.org
Ease of cleanup (as it falls in a nice line, instead of a giant pile) and predictability in how it will fall (so it doesn't crush nearby buildings/walls/etc. Plus it's cheaper than designing and executing a controlled explosion.

People have been cutting down big trees that that was for thousands of years. It's only dangerous if you do it wrong ...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
