AI Thread Summary
Idling refers to running an engine at a slow speed without any load. It is characterized by both conditions of low speed and no load, meaning revving the engine while not under load does not qualify as idling. In vehicles with automatic transmissions, the car may move forward slowly even when the engine is idling. Idle speed is defined as the minimum speed at which the engine can operate without stalling or shaking excessively. Understanding idling is essential for proper engine management and efficiency.

Idling means running an engine at slow speed when it is not on load.

Most situations require both conditions (slow and no load) so revving the engine whilst not on load is not idling.

However cars with automatic gearboxes will drive foward slowly when the engine is 'idling'

Another way to look at it is to say that idle speed is the slowest speed the engine will run at without stalling or rocking violently.

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.

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
