Q.  
In a Hooke’s joint, the driving shaft rotates at constant angular speed but driven shaft rotates at


Answer & Explanation

The driving shaft rotates at constant angular speed but driven shaft rotates at varying speed which gets it maximum value two times in each revolution.

Thus correct option is: D.
