The discussion revolves around understanding how a leather belt functions to hold up baggy jeans, with a focus on the effects of various changes to the belt's dimensions and materials. Participants explore the role of friction in this context.
The conversation is ongoing, with participants offering insights and asking clarifying questions about the principles of friction and its application to the problem. There is a recognition of the need to explore various factors that could affect the frictional force.
Participants are considering the implications of different belt characteristics and their effects on friction, while also referencing comparisons to other mechanisms like hose clamps. There is an acknowledgment of the need to refer to relevant formulas related to friction.
Okay. Can you explain why friction matters in this problem? Supposing that it does matter, what else can affect the friction? What about the "variables" mentioned in the problem statement?Fizzic said:Reducing diameter of the belt by tightening inreases friction?
Is that true? Sounds more like what glue or an adhesive does. Perhaps you meant that friction opposes the sliding motion of one surface over another?Fizzic said:Friction keeps things from moving apart?
You should check the various formulas that apply to friction (refer to your text or course notes). How is friction related to force, pressure, and contact area?Smaller area of narrow belt would mean less friction.
That sounds like a good idea.Trying to compare to action of hose clamp.
