and this means .
Same idea with which is .
The only other thing you need to know is the force T has a magnitude of 500N.
I'm having trouble solving this. My process is as follows:
- Find a unit vector in direction of C to E
- Find components of T using the unit vector from C to E
- Find vector r from B to C
I then used the cross product of rBC x T, and am not getting the correct answer.
I'm getting: 33.4i -124.98j - 183.43k (Nm)
The answer is: -12.0i - 138.4j - 117.4k (Nm)
