How to determine position vector.

AI Thread Summary
Determining the signs for a position vector depends on the reference point chosen, typically the axis of rotation or the point of application of force. The position vector is defined from the point of application of force to the axis of rotation. Understanding the direction and magnitude of the vector is crucial for accurate calculations. Further clarification may be needed to address specific scenarios or applications. For more detailed guidance, researching Kane's notation can provide additional insights.

Hi guys.I n moment,Im confused as to how to determine the signs that go next to the position vector.On what thing do they depend?Do we take the position vector from point of application of force to axis of rotation or otherwise?EDIT:If I am not being specific enough please say so guys.I really need to know this.

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 '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...
