The direction of Coriolis’s component of acceleration is obtained by :
1
Rotating V (Velocity of slider w.r.t. coincident point) at 180 degrees about its origin in the same direction as that of of (angular velocity of the slotted lever)
2
Rotating V (Velocity of slider w.r.t. coincident point) at 90 degrees about its origin in the same direction as that of of (angular velocity of the slotted lever)
3
Rotating V (Velocity of slider w.r.t. coincident point) at 90 degrees about its origin in the opposite direction as that of of (angular velocity of the slotted lever)
4
Rotating V (Velocity of slider w.r.t. coincident point) at 270 degrees about its origin in the same direction as that of of (angular velocity of the slotted lever)
