Homework Equations
T=F⊥r
The Attempt at a Solution
I know that I need to add the three( the bar, the wire, and weight, but I'm not sure how to do that. I tried...
0= Tbar+Twire+Tweight
0= Tbar+Twire+Tweight
0= Tsin30+1200sin30+400sin30⋅9.8
I'm not sure if I did this correctly. The options for answers are
A) 6640N
B) 1600N
C) 3320N
D) 4200N
E) 2750N
The first answer that i got using another method was 3320. That was wrong.
