3.5 feet long rotates in a horizontal plane about a vertical axis through its center. At each end of the rod is fastened a cord 6 ft. long. Each cord is inclined at Ø = 450 with the vertical and supports a weight of 45 lbs A. Which of the following gives the speed of rotation “n” in rpm? a) n = 25.12 rpm b) n = 25.12 rpm c) n = 30.20 rpm d) n = 22.13 rpm
