I had my teacher explain this question to me and I don't know why phantomJay thinks the second rod isn't under tension when it clearly is.. to find the tension you just have to select a point and find the moments around that point which will give the tension on on rod, you than subtract that...

I tried the question and this is what I got: (490)(.55)=(Ta)(.60) 269.5=(Ta)(.60) 269.5/.60=Ta Ta=449.167 Tb=490-449.167 Tb=40.83+20 Tb=60.83 So Ta=449.167 Tb=60.83 Im not sure if I am right...what do you think

Homework Statement Heres the question: The picture is not to scale I am suppose to find the tension of both Ta and Tb I have posted this question several time on different sites and no one seems to be able to answer it for me...If you can show me the process in doing this question I...

You are on the right track i had my teacher explain it to me and the answer is actually 0.0874

This question is right out of a physics textbook

I know the question is right...If anyone can explain how to do it I would really appreciate it

I really still don't know where to start can someone go over the steps in doing this question Thanks

Homework Statement Obviously the picture is not to scale The Attempt at a Solution I really have no ides where to start I assume you have to use moments to find the tension in each cable but I am really not sure how to go at it. I think the 20 N force hanging from the sign...

Sorry i didnt really mention that...It is out of a textbook and it is not scale..dont know why so just ignore the scale

Awsome...Thanks

Yes those are the dimensions...its just really out of wack for the question obviously no one would build a sign like that

Homework Statement A 135 kg sled is being pulled along a horizontal surface at a uniform speed by means of a rope making an angle of 19.3 degrees with the horiontal. If the tension in the rope is 119 N Find the Coefficient of friction. Homework Equations u=Ff/Fn The Attempt at a...

Homework Statement Homework Equations The Attempt at a Solution I really have no ides where to start I assume you have to use moments to find the tension in each cable but I am really not sure how to go at it. I think the 20 N force hanging from the sign would only act through...
