Three strings are tied together at one end. The other ends are attached to a rectangular frame as shown below:
The tensions in the strings are labeled Tx, Ty, and Tz. The tension in the vertical string is Tx=47.0N. Angle A= 58.5 deg, and angle B= 30.5 deg. Calculate the magnitude of the tension Tz.
Tz + Ty + Tx= 0
my TA gave me this one: Ty/sin(A+B) = Tz/sin(90-A)
The Attempt at a Solution
I tried a number of things, thought maybe the tension in Tx would carry through in the y-direction so I could use that as the y-component to make a triangle with Ty, so I could find Ty and use that in the equation my TA gave to me, but that didn't get me the right answer and I got it wrong on the homework assignment. Can anyone help me on finding Ty or give me some sort of step by step process to follow to get the right answer?
