jack action said:I know the coefficient of friction can be greater than one. But it seems that a lot of people were thought the opposite at some point through the school system. What was the reasoning behind that theory? I can't imagine how you could prove such a statement.
Interesting question, and probably no really clear answer. It did include contact area, forbade galling and adhesion (which would have wiped out any basis for proposing the "unit" limit in the first place), and made some strange appeal to intuition based on 45 degree frictionless (of all things) wedges, and it's just as well I can't recall the particulars. It made for entertaining evenings in college, listening to adherents vs. drag racing fans.jack action said:What was the reasoning behind that theory?
µ < 1 is a mathematical notation commonly used in statistics to represent a value less than 1. It is also known as a "subunit multiplier" and is often used to express proportions or rates.
In scientific research, µ < 1 is often used to represent a small effect size. This means that the relationship between two variables is weak or negligible. It is important because it helps scientists determine the significance and practical importance of their findings.
Using µ < 1 in statistical analysis allows researchers to identify and interpret small effects in their data. It also helps to avoid overstating the significance of results and allows for more accurate conclusions to be drawn from the data.
µ < 1 and p-values are both measures used in statistical analysis to determine the significance of results. However, while p-values indicate the probability of obtaining a result by chance, µ < 1 represents the size of the effect and the strength of the relationship between variables.
No, µ < 1 cannot have a negative value. It is a measure of proportion or rate, and negative values do not make sense in this context. If a value is less than 1, it will always be positive.
