Question 11
Homework Equations
T_net = 0
F_net = 0
The Attempt at a Solution
Start with F_net = 0:
Let T1 be the force of tension on the left, T2 on the right
T1cosθ=T2cosθ
Y components:
T1sinθ+T2sinθ = mg
Since T1 = T2, as established by the x-component force equation:
2T1sinθ= mg
T1sinθ = mg /2
Now let's look at T_net = 0
Take the leftmost point to be the PoR
This is where I got stuck.
T1cosθb = T2sinθa
T2sinθ=T1sinθ = mg/2
T1cosθb = mg/2a
a/b = mg/2T1cosθ
I'm really confused about how to find the torque:
I get that it is rxF or rFsintheta but I'm struggling to make the equation.
