Articulaied un-rollcr support- in this suppons simplc responsc action is unkno\sTi. The rcaction system dccomposcs into iwo independent componcnts of H_A and V_A. Ha is the horizontal rcaction and V_A is a ycrticał rcaction.

Articulated rollcr support- in thc support of this we arc dcaling with one unknown rcaction of V_A. a simplc action is perpcndicular to thc dircction of motion. An cxamplc of such bonds arc no frictional sliding connection (idcally smooth surfaces).

Fixcd support- simplc action of rcaction is unknown. In thc case of fix apart front the rcaction forcc R decomposcd into two componcnts H_A and V_A must be applied fixcd moment M_A.

Fixcd support with the horizontal displacentent (tclcscopic connection) - The name of this typc comcs front the fact that the chains prevents the rotation and vertical ntoventent.
