AI Thread Summary
Rotary wheel-like appendages refer to devices that operate on wheel principles but are not classified as wheels, such as rotary paddles. In the context of a competition, the rules prohibit using wheels or any similar devices for locomotion. Participants are encouraged to explore alternative locomotion methods inspired by nature, which has successfully achieved movement without wheels. Suggestions include using mechanisms like tracks or legs instead of traditional wheels. The discussion emphasizes the need for innovative solutions within the competition's constraints.

what is "rotary wheel-like appendages"

what exactly do you mean by "rotary wheel-like appendages" what does it mean that we can not use rotary wheel-like appendages?... then what can we use?

Presumably, this is part of a description for building a device for a competition?

The rules are forbidding the use of wheels for locomotion. It is pretty easy to create a device that operates on the same principle as a wheel but that is not called a wheel (such as rotary paddles, like a propellor turned sideways for traction). The rules are forbidding all such devices.

Think of other forms of locomotion. Nature has done a fabulous job of achieving locomotion without ever managing to have invented the wheel-and-axle.

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

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...

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
