💁🏻‍♀️ TIL: Garbage #trucks use hydraulic systems, robotic arms, and compactors to lift, crush, and haul tons of #waste.

Experts explain rear-load and side-load trucks, from the first automated model in 1969 to today’s electric fleets. Every truck repeats the collection process hundreds of times per route before heading to a landfill.

Flood Vulnerability And Load Capacity Assessment Of Historic Masonry Arch Bridges In Ireland Under Changing Climates

H/T @Upaka Rathnayake
“HIGHLIGHTS:
• Field surveys and flood modelling were used to evaluate the resilience of eight historic masonry arch bridges in County Offaly, Ireland, under projected fluvial flooding conditions.
• Results indicate that increased flood levels and hydraulic forces can significantly reduce bridge load-carrying capacity, with potential reductions of up to 40% due to buoyancy effects during extreme flood events.
• The study demonstrates a clear relationship between flood exposure and structural deterioration, emphasizing the need for structural health monitoring, maintenance strategies, and climate-resilient infrastructure management…
ABSTRACT: Masonry bridges, predominantly constructed from stone or brick, were a common feature of bridge engineering during the 18th and 19th centuries. However, these historic bridges are still in use today, but they are at risk due to various extreme climate conditions. Thus, these bridges are vulnerable to damage and needy for investigation. This paper offers an in-depth analysis of the projected impacts of fluvial flooding stemming from climate change on a number of masonry arch bridge structures located in county Offaly, Ireland. It evaluates bridge resilience by examining estimated flood levels alongside the overall condition of the structures. These assessments play a crucial role in determining the load-bearing capacity of the bridges and whether adjustment factors should be implemented. Particularly for bridges situated on primary and secondary roads with consistent heavy goods vehicle (HGV) traffic, the potential decrease in load-bearing capabilities warrants significant consideration. This study highlights concerns regarding the resilience of these historic structures and presents a valid argument regarding their suitability for contemporary environmental conditions and present-day activities…”

Interesting. In isolation, making the end of the hose smaller with your thumb should not matter (the flow rate should be the same). In practice, it does, because using the thumb affects the flow rate of the system. You'll also learn info on pipe engineering.

Trying out my new I2C-equipped solenoid drivers and ADCs I got for the hydraulic robot. I am ready to control a bajillion valves ... #robotics #hydraulics

Only found four of the partial thread bolts and they were too long, meaning the threaded section started too late.

Slapped the wheel back together with some incorrect bolts for now and wrestled the old leaky inner tube back in just so I can roll the trailer out of the way as I need the tractor.

This took way too long, but on the upside, a lot of junk got sorted in the process.

And some treasure, too. A mountain of bolts, nuts and lock washers, some banjo bolts, a crappy mallet, a fire axe and drill, and a few tractor parts including starter motor, hydraulic pump, two alternators, etc.

The hydraulic pump is a great find, those aren't cheap and it looks in decent shape.

Success #2: I do seem to be able to heat-fuse 3D-printed polypropylene with my polyethylene film. Despite being technically different materials, these are a lot more willing to be friends than PLA and PE. #robotics #hydraulics

First try sealing polyethylene film to a polyethylene tube, and it worked out! Besides matching materials, I needed pressure - the heat gun alone won't do it. Had to use the soldering iron behind aluminum foil. #robotics #hydraulics

When two cavitation bubbles of different sizes collapse, they form distinct jet patterns that affect local pressure and energy distribution.

Understanding these dynamics helps predict damage in hydraulic systems.
