**Find tension T1, tension T2, tension T3, tension T4, tension T5 and the magnitude of force vector F.**

**2. Homework Equations**

T=ma

**3. The Attempt at a Solution**

I have figured out every single tension except for T_4 and it has me stumped.

Here are all the other answers

t_1=ma

t_2=((ma)/2) = t_3 = t_5 = "Magnitude of Force F"

t_4 has me stumped however. I thought it may be ((ma)/3) since it was being held up by t_2, t_4 and t_5 but that was wrong. Could anyone either explain it to me or link me to a decent explanation?

edit: i realize i included no numbers for my correct answers.

"m" times "a" comes out to 137.2N
