Example 7 3 A threaded rod with 12 turns per cm and diameter 1 18 cm is mounted horizontally A bar with a threaded hole to match the rod is screwed onto the rod The bar spins at the rate of 216 rpm Determine the velocity of the bar with which it will move the length of 1 50 cm along the rod Also find the time taken by it 216 Sol Given frequency n 216 rpm rps 60 1 Length of one turn cm 12 Number of rotations required to move a distance of 1 5 cm Distance 1 5 N 18 Length of one turn 1 12 Therefore angular displacement 0 2 N 2 Angular velocity of the bar w 2 n 2 x Required time t 36T x 18 36 tra 216 60 7 2 rad s 1 Angular displacement 0 Angular velocity w
