In CAD, rotate the U-shaped link to align with the direction of the applied force. If there is clearance between the hole and the pin, then move the U-shaped link along the line of force until the hole and pin are tangent on the opposite side of the hole from the direction of the force.

In Mechanical, change the Bonded Contact between the holes in the U-shaped link and the pins in the holes to Frictional Contact. Under the Connections folder, insert a Contact Tool and Generate Initial Contact Status.  The Frictional Contact must be closed before you start the simulation.
