Explanation:

  • Coriolis component of acceleration exists when there is a sliding motion of a slider which is sliding on a link which itself is rotating.
  • In the case of the shaper, the quick return mechanism is used which has a slider sliding on the rotating link. So the Coriolis component of acceleration exists.
  • The  Coriolis component of acceleration depends on the crank position. As at the extreme ends, the angular velocity of the crank is zero and so the Coriolis component of acceleration is also zero and at the centre velocity of sliding is zero again Coriolis acceleration is zero. So it depends on the crank position.
