How Do You Calculate Tension Forces in a Hanging Weight Problem?

[mrserv0n]

Let me try to draw this out

--------------------- <-- R2 <30degree
\ R1<50degree /
\ /
\ /
\ /
\ /
\ /
\ / T2 is acting north along the 30 degree (R2)
| T1 is acting north along the 50 degree (R1)
|
|
W=300N

Problem: a 300-N weight is hanging from the ropes R1 and R2. Obtrain the tension forces T1 and T2 acting on the weight.

I have a test in 2 hours and no clue how to solve this problem. I have figured out the 6 others study ones for the most part but need someone to help do this

It appears u can draw it doesn't keep it in tact its basically a triangle upside down with a weight hanging from it

Those problems are always dealt the same way:

a) Draw a y and x-axis (here the obvious choice is to put the x-axis aligned East-West)

b) Decompose all the forces into their x and y components

c) Apply \sum F_x = m a_x and \sum F_y = m a_y. In this example, the x and y components of the forces add up to zero.

d) You have two equations and two unknowns (at most). Solve for what you are looking for.
