Homework Statement
In the speed-governing mechanism m = 0.2 kg, L = 10cm, (rods AB have negligible mass), w = 500 rpm, θ = 40°,θ' = 0 . Determine θ'' at that instant and the tension in the rod.
Homework Equations
F=[ω][/2]r
The Attempt at a Solution
First, I calculated ω = 500 rpm * 2π /60 = 52.36 rad/s.
From the vertical components, I determined T*cosθ = mg
So T = 2.56 N
With this, I can calculate the horizontal component of T, but then I have a different ω for the balls and I'm confused. Should I use polar coordinates? If so, how should I start?
