Crate on a cable statics question

Homework Statement

Please refer to the attachment.

Homework Equations

Sum of x and y forces = zero
Sum of moments about any point = zero

The Attempt at a Solution

By looking at the portion of the string under the crate, there are 3 forces acting on it, namely the two tensions at the side and the weight of the crate. Hence I deduce that the gravitational force of the crate acting on the string is the sum of the two vertical components of the tensions.

Can anyone tell me if I'm right or am I missing out on any forces?

Please help, thanks much!

You are correct. Next you'll have to use a little trig to find the angle that the cables make.

oh i got the angle already, I was just confused as to whether there were any more forces acting on it. thanks for the clarification!
