Question

The sense of Coriolis component 2ωV is the same as that of the relative velocity vector V rotated.

(a) 45^0 in the direction of rotation of the link containing the path

(b) 45^0 in the direction opposite to the rotation of the link containing the path

(c) 90^0 in the direction of rotation of the link containing the path

(d) 180^0 in the direction opposite to the rotation of the link containing the path

I had been asked this question in an international level competition.

Origin of the question is Forces Acting in a Mechanism topic in section Velocity in Mechanisms of Machine Kinematics

Answer 1

Right answer is (c) 90^0 in the direction of rotation of the link containing the path

Easiest explanation: The sense of Coriolis component 2ωV is the same as that of the relative velocity vector V rotated 90^0 in the direction of rotation of the link containing the path.

The direction of coriolis component is along a line rotated 90^0 from the sliding velocity in a direction same as that of the angular velocity of the slotted lever.
