Q.  
The distance between two parallel shafts is 20 mm and they are connected by an Oldham’s coupling. The driving shaft revolves at 180 rpm. What will be the maximum speed of sliding of the tongue of the intermediate piece along its groove?


Answer & Explanation

Given:\n Shaft revolution N=180 rpm\n Distance between two shafts r= 20 mm=0.02m\nAngular velocity of shaft (ω):\nω = 2πN/60\nω = 2π(180)/60\nω = 18.85 rad/s\nThe maximum speed of sliding:\nv = r*ω\nv = 0.02 * 18.85\nv= 0.376 m/s

Thus correct option is: C.
