Question

In the figure shown a smooth ring is connected to rod AB, while rod CD passes through ring. At the given instant angular velocity of rod AB about hinge A is and, instantaneous angular velocity of rod CD about hinge C is

Answer 1

$answer$

Here is the solution.

Answer 2

Answer:

given =  refer the given diagram

             ring is connected to rod AB,

             rod CD passes through ring.

            rod CD about hinge C  

solution = velocity have same component. velocity of contact point on rod CD  and ring should have same component of velocity along normal to rod CD

BC(ω) = 2(BCcosθ)ω cosθ

ω " = 2ωcos²θ

ω"= 3/2rad/s

so the angularr velocity of rod AB  about hinge A  is  3/2rad/s
