Two identical discs of same radius R are rotating about their axes in ...
Draw tangents to the circles at P and Q and at the top and bottom of the circles and mark the direction of motion on each.
As, both speeds are equal and at P and Q, the direction of motion is the same, relative speed is 0.
At the top and bottom of the path, the direction of motion of each of them is opposite to that of the other. Thus, relative speed increases.
At the diametrically opposite positions to P and Q, again the motion is in the same direction and the speeds are equal, so, relative speed is 0.
Thus, the relative speed increases from 0 to a maximum value as the discs rotate from P and Q to the bottom of the path , then it decreases to 0 as they rotate from the bottom to the diametrically opposite positions to P and Q , and again increases as they rotate to the top and finally becomes 0 as they come back again to their original position.
As, both speeds are equal and at P and Q, the direction of motion is the same, relative speed is 0.
At the top and bottom of the path, the direction of motion of each of them is opposite to that of the other. Thus, relative speed increases.
At the diametrically opposite positions to P and Q, again the motion is in the same direction and the speeds are equal, so, relative speed is 0.
Thus, the relative speed increases from 0 to a maximum value as the discs rotate from P and Q to the bottom of the path , then it decreases to 0 as they rotate from the bottom to the diametrically opposite positions to P and Q , and again increases as they rotate to the top and finally becomes 0 as they come back again to their original position.
