In a crank and slotted lever type quick return mechanism, the link moves with an angular velocity of 20 rad/s, while the slider moves with the linear velocity of 1.5 m/s. The magnitude and direction of Coriolis component of acceleration with respect to angular velocity are

(a) 30 m/s^2 and direction is such as to rotate slider velocity in the same sense as the angular velocity

(b) 30 m/s^2 and direction is such as to rotate slider velocity in the opposite sense as the angular velocity

(c) 60 m/s^2 and direction is such as to rotate slider velocity in the same sense as the angular velocity

(d) 60 m/s^2 and direction is such as to rotate slider velocity in the opposite sense as the angular velocity.

My question is based upon Four Bar Chain or Quadric Cycle Chain topic in division Simple Mechanisms of Machine Kinematics

The correct option is (c) 60 m/s^2 and direction is such as to rotate slider velocity in the same sense as the angular velocity

Best explanation: Magnitude of Coriolis acceleration = 2Vω

= 2 x 1.5 x 20

= 60 m/s^2

Rotate the link in direction of rotation and see the direction of linear velocity that will be direction of Coriolis acceleration.
