A small 8-oz collar D can slide on portion AB of a rod which is bent as shown. Knowing that the rod rotates about the vertical AC at a constant rate and that a = 40° and r = 24 in., determine the range of values of the speed υ for which the collar will not slide on the rod if the coefficient of static friction between the rod and die collar is 0.35.
