1. Homework Statement

1. Homework Statement

The tension in the supporting cable AB is T = 425 N. Write this tension as a vector (a) as it acts on point A and (b) as it acts on point B. Assume θ = 30°. [***I've attached a picture of the exact problem]

The answer in my text book says

**T**= <221, -212, 294>

_{A}**T**= <-221, 212, -294>

_{B}## Homework Equations

^{→}**AB**) / (||

^{→}**AB**||)

^{→}## The Attempt at a Solution

I started by finding the

**AB**which I used A = (0, 5cos(30), 5sin(30)) and B = (2, 0, 6), which gave me

^{→}**AB**= <2, -4.33, 3.5>.

^{→}Next I used

**n**= (

^{→}**AB**) / (||

^{→}**AB**||) to find

^{→}**n**= <.338, -.732, .5916>

^{→}Then I found

**T**= <143.65, -311.1, 251.43>

^{→}**= (T)(n**^{→})I'm not sure what I'm doing wrong here. The only thing I can think of is if I'm using incorrect points for point A
