Coriolis component of the acceleration is experienced:

Explanation:

Coriolis Acceleration

• If the distance between the two points does not remain fixed and the second point slides, the total acceleration will contain an additional component of acceleration, known as Coriolis Acceleration.
• Coriolis component of acceleration is equal to 2vω, where, v is the sliding velocity and ω is the angular speed. 
• The direction of Coriolis acceleration is such as to rotate the slider velocity vector in the same sense as the angular velocity of the link.
• This acceleration is experienced by a point on one link that is sliding along another rotating link.
