1. The problem statement, all variables and given/known data http://[URL=http://www.siz.co.il/][PLAIN]http://up416.siz.co.il/up3/w2jymjm5nqxy.png [Broken] A body with a mass that equals to m is inside a smooth tube and is attached to two identical springs with constants that equal to k. Their length when they are limp is L0. When the body is in the middle of the tube both springs are limp. The tube is attached to a pole that spins around with an angular velocity that equals to ω (The motion is only horizontal) 1. In what distance the body needs to be from the center of the tube so he will spin around along with the tube without moving in relative to him? Answer: mω2L0/(2k-mω2) 2. Now we attach the tube in an angle of 37 degrees to the pole (α=37 degrees), what the angular velocity ω0 needs to be so both springs will remain limp? 2b. The angular velocity in increased to 2ω0, in what distance the body needs to be from the center of the tube so he will spin around along with the tube without moving in relative to him? Honestly I tried a lot but I can't seem to solve the first question, can anyone help please? Sorry for my English, I know it's very poor. Equations: mar=F ar=ω2r F=KΔL ma=F How I tried to solve this: I tried to say that the force that the springs enables on the body is 2KΔL, but it didn't work.
