Solve Angular Velocity when Initial Theta=30º, Bar Mass=m, AB=L/2, BC=L/2

[Mr. Leal]

Homework Statement

the problem gave a initial θ=30º, bar mass=m
they want to know the angular velocity when θ=0º
AB=L/2 and BC=L/2

My attempt:
rest in the inicial state, so: v=0, w=0 and T1=0
using conservation of energy and V=w*L/2
I can find w( angular velocity)
bit I'm not quite sure that this is the right metod

thanks

I don't know what your w, V, v and T1 are but your basic idea is correct.
