Homework Statement How much frictional torque is there? I know angular acceleration and torque applied. (I do not know if this can be used to find torque friction, though.) Homework Equations The Attempt at a Solution I know that Frictional torque can be found by doing Torque...

thanks for the help I really appreciated it, I never expected such a fast response ot my question! :)

for some reason i accidentally inserted a middle force of the ruler :/ for the most part my calculations were on the right track, but I was totally off on the rotational equilbirum

ok, so I did Tccw=Tcw Tsin40(1.015)= 20(.5075)+(37.5)(.25) ...=29.93 N and that's the tension in the string Tnet= -29.93(sin35)(.25)+ 20(.5075)+ 37.5(.25)= 19.78 N-m

umm how exactly do I do that??

I solved for perpendicular tension and net torque, where do I go from there?

its .25 meters from the right hand side of the triangle

Thanks for the welcome! So, I uploaded the picture to ==> http://www.esnips.com/doc/213a83ad-c990-4667-af39-a58d8777a0cc/Diagram Don't know if it'll work so I'll describe the picture as best as I can! The picture is representative of a right triangle. There is a piece of string...

Homework Statement **picture located as attachment** Homework Equations Tccw= Tcw The Attempt at a Solution My biggest problem is that I don't know what components are needed to find the coefficient of friction. I am able to find things like the tension/force of the string, but...
