And I'm starting to feel kind of dumb here...
here is the picture to go along with the question
Question: Draw a free-body diagram for Point A, showing all the forces acting at A.
Resolve the vectors into components, where necessary.
Using the first condition of equilibrium, solve for T1 and T2.
Repeat for Point B, and solve for T3 and T4 .
So what I've done is realize that the sum of forces on the y-axis should equal zero, so I have written that T4Sin35 + T2Sin65 - 80.0N = 0
What I've learned is that you have to substitute in a value for T4 or T2 so you can then solve for the other one. Problem is I'm not sure how to approach this since there are two separate strings on the x axis.
I have it written that T2cos65 + T4cos35 - T1 - T3 = 0, but I'm not sure if that is right.
A little direction here would be immensly appreciated.
Thank you so much! (sorry it's not written in TeX! I plan on learning it but have been so busy with school and haven't found the time yet.)
