#536 Friction Wedge
How do you know where to exactly put or locate R (reaction)? Is there a rule?

In reply to #536 Friction Wedge by Benjamin_Molina
R is the resultant of normal reaction N and the friction force f. The direction of R depends on the the direction of friction. Friction is the component of R parallel to the plane of contact.
The figure below below shows R for friction directed down the plane of contact.
If the friction force is directed up the plane, then R would be as shown below.
I hope that cleared you up.

Thank you so much Engr. Verterra. That was a big help.

why is it that B has friction force when it is stated in the problem that B is at rest?
