1. The problem statement, all variables and given/known data A ball of mass m is attached by two strings to a vertical rod. as shown in the diagram attached. The entire system rotates at constant angular velocity ω about the axis of the rod. a)Assuming ω is large enough to keep both strings taut, find the force each string exerts on the ball in terms of ω, m, g, R, and θ. b)Find the minimum angular velocity, θ_min for which the lower string barely remains taut. 2. Relevant equations F_centripetal=mv2/r F=ma 3. The attempt at a solution A) To keep the strings taut, the net force in the y-axis and the x-axis have to both equal 0. I used forces and tension, but my answer didn't contain ω, but I feel like it should... T1 tension is making θ angle with the vertical T1cosθ along vertical upward T1sinθ along horizental i.e towards the center of the circular path applying ΣFy =0 ΣFx =0 T1cosθ=mg T1=mg/cosθ T1sinθ+T2=mv2/R T2=mgsinθ+mv2/R B) I would solve for v from the equations above, but the question doesn't say that I can use T (tension) in my answer... What am I doing wrong in this problem? Thanks in advance!
