Components for Slot-Follower Connection Reaction Measures
You can select one of the following components for a slot-follower connection reaction. All components are relative to a Cartesian coordinate system.
Force X—Measure the force along the X axis exerted when a slot follower reaches one of the endpoints of the slot.
Force Y—Measure the force along the Y axis exerted when a slot follower reaches one of the endpoints of the slot.
Force Z—Measure the force along the Z axis exerted when a slot follower reaches one of the endpoints of the slot.
Total force—Measure the total force that is exerted when a slot follower reaches one of the endpoints of the slot.
Normal—Measure the force due to friction that is exerted normal to the slot follower at the point of contact with the slot curve.
Tangential—Measure the force due to friction that is exerted tangent to the slot curve, in a direction opposing the movement of the follower along the slot curve.

You must specify friction coefficients when you create your slot-follower connection, and enable friction for the analysis, to measure Normal and Tangential components.
