Webpage title: Solving for Tension in a Rope Problem

[jarmen]

so T1, 80*, =3253.7N

T2, 65*, =1336.9N

does this look right, seems like quite a bit of tension

 

[jarmen]

i tried those answers but they were incorrect.

 

[Sdawg1969]

no- I think we did something wrong. T1+T2=565N so you could say

T1=565-T2

 

[jarmen]

ok, then how do i find T1 or T2

 

[Sdawg1969]

I messed you up more then I helped, sorry man. I need my notes/book/calculator and they are all in my car.. sorry to take you down the wrong track like that

 

[Sdawg1969]

ok, if both lengths of rope were equal

T1=Fg/2

T2=Fg/2

they are not but this gives me an idea...

 

[jarmen]

ok...

There are three forces acting on the person:
- Tension (T1) from left rope (acting at the angle of the rope)
- Tension (T2) from right rope (acting at the angle of the rope)
- Weight (W) acting down (which is given)

Since she's in equilibrium:
- The sum of the vertical force components must equal 0
- The sum of the horizontal force components must equal 0

That will give you two equations, which you can solve to find the two unknowns: T1 & T2.
