Marine props have had variable pitch blades since last century dating back to 1940.

Most USN GTM powered ships are like this also for speeds 0-13kts. Blade angles change at constant shaft rotation to change speed. Above 13kt is strictly rotation speed.

Installing a ship propeller involves precision alignment, hydraulic jacks, and expert divers or drydock operations. Each propeller—often weighing several tons—is custom-fitted to the shaft, ensuring optimal thrust and fuel efficiency. A true feat of marine engineering!

Direct-Drive Aircraft Propulsion In most piston-powered aircraft, the propeller is bolted directly to the engine's crankshaft. Engine power is transmitted without gears, belts, or chains, allowing the throttle to control both engine and propeller RPM simultaneously. This direct-drive configuration simplifies the powertrain while reducing weight and maintenance. 🎥 prath1001

President Trump is changing more than policy. Beneath the headlines, something deeper is happening—a renewed belief that America can solve problems, build again, and shape its own future. Here's why that matters.

SP seems to be very good at one thing: changing its tone after an election loss. Suddenly, there is talk about women, safety, justice, and concern for the very issues that their govt struggled with during its own time in power. This video is not about arguments or political debates. It's simply a reminder what UP looked like then, what leaders said at the time, and the families who had to suffer through it all. Rebranding and changing the language may create a new image, but people's memories don't change that easily.

I saw a The New York Times story about New York City trying to use birth control to combat its rat problem, so I had Google Gemini write lyrics about it and and Sonu AI turn it into a disco song. I'm not 100% sold on AI changing the way we work, but it is changing the way I waste time.
