1. The problem statement, all variables and given/known data 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. 2. Relevant equations F=[ω][/2]r 3. 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?
