I found interesting to me this topic and tryed to analyze.

At which angle it is eseaiest to pull an object?
I got equation
[tex]F=\frac{\mu mg}{cos(\alpha)(\mu tan(\alpha)-1)}[/tex] or [tex]F=\frac{\mu mg}{\mu sin(\alpha)+cos(\alpha)}[/tex]
I don't know this math very well unfortunately, but I would be interested to see a plot:
how mostly optimum angle is dependent from mu, and for example then mu is 1 alpha is 45, and so on...
heh sorry for the paint and spelling...
