1. A 1400kg steel beam is supported by two ropes. Find the tension of each rope.
Rope 1 is 20 degrees from the vertical axis and Rope 2 is 30 degrees from the vertical axis.
2. I am getting lost trying to find the vector components of each rope. More specifically, I am having trouble solving the system of equations as I can't remember the last time I've done this.
Here's my set-up:
T1cos(20) + T2cos(30) = 13720
T1sin(20) + T2sin(30) = 0
When I solve the system of equations I get T1=39505 and T2=-27023. These do not seem to be the correct answers according to MasteringPhysics, and if I'm not mistaken they don't make sense either.
