A rigid T consists of a long rod glued perpendicularly to another rod of length l that is pivoted at the origin. The T rotates around in a horizontal plane with constant frequency ω. A mass m is free to slide along the long rod and is connected to the intersection of the rods by a spring with spring constant k and relaxed length zero (see Fig. 6.27). Find r(t), where r is the position of the mass along the long rod. There is a special value of ω; what is it, and why is it special? http://s3.amazonaws.com/answer-board-image/628ae3fdb906a2b8b95fb53923eb34c7.jpg

anonymous · Answer

w=2(pie) x cyclic frequency, 
w=square root(K/m) K is spring constant and m is mass
I not sure how exactly are they different

anonymous · Answer

Angular frequecy is that "w"
Cyclic frequency F=1/2(pie)xsquare root(k/m)
