Torque needed to overcome friction and move object

Main Question or Discussion Point

I need to calculate the torque needed to move an object in horizontal direction. The object is subjected to a force P also in horizontal direction. The general situation is as follows: a (hor.) lever is connected to a (vert.) shaft which will provide the torque. The other end of the lever is connected*to the object. Now, my problem lies in understanding the torque needed to move the object for different types of connection between lever and object. There are 3 situations: connection is a hinge* or there is no fixed connection but the lever can slide against the surface of the object with a high* friction coefficient or very low* coefficient. So, apart from the force P applied to the object, the lever also has to overcome the force due to friction with the object surface or the force on the hinge.

Where does the friction of the object occur?
Can you add a sketch of your setup(s)?

At least for me, the problem is quite unclear.
