Question

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.

I had been asked this question in homework.

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

Answer 1

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.
