Good job sir, but I feel that answer for the last question is wrong, it is 50 and not 5 rad per second

[@yasirosmani695]

48:27 it will be 0.04 (40 mm) in calculation of angular velocity and answer will be 50 rad/sec. It can also be solved using the idea of epicyclic gear train assuming the sector to be the arm, central gear as sun and both outer gears as planet gears.

Amazing sir...

I understood the concept of instantaneous center but I am not convinced about the answer for the angular velocity of smaller gear(since it is not mentioned the point of reference here). With my knowledge in gear trains I have found that the answer is quite contrast(44rad/sec).

[@pratapkumarmishra8297]

That's the angular velocity of rotation around large gear. This is angular velocity of rotation on it's own fixed axis

Ans for last question is 50ccw

[@nishabhatt8527]

Have you got the answer? I have same question?

[@mindblowing669]

Idk if it's still gonna be helpful but how u do it is by parallely shifting the axis to the fictitious point A . Then calculating the angle of the absolute velocity vector of A with those axis ​which comes out to be 30° with vertical . Then u just write those unit vectors.@@nishabhatt8527
