# Homework Help: Find Tension of the wires

Ok here the problem i need to find the tension of the three wires but im very lost and don't know where to start or how to finish.

so for i got 32*98 = 313.6N
i don't know what to do next
can someone please lead me in the correct direction to solve the problem.

First thing you need to do is to resolve all the tensions into triangular forces i.e translate a vector so you can treat the three tensions as applying the triange law for vectors
$$\vec{ac}=\vec{ab}+\vec{bc}$$

ok so i have Fnet=M*a

so for the tension on the rock i have a tension and a weight
so

ball
\/ t1

/\ t1

so would this be the correct equation to solve for T if it is what would the acceleration be because its not give or i don't think there is anyway to find it

T1=313.6 * A

Before even attempting to solve for T you must resolve each tension into it's components. Simply applying a formula here is almost useless.
I must also apologies for not being able to understand what exactly you mean by the diagram
\/ t1

/\ t1
A isn't given, but it's a safe bet to assume that gravity is present.
