2. Mechanism Mechanism consists of linkages and joints.
Mechanism is an assembly of rigid elements (linkages) arranged and connected to form a closed kinematic chain with one link fixed in order to transmit motion in a predetermined fashion.
Mechanism consists of linkages and joints.
Machine is an arrangement of parts for doing work, and applying power .
Structure is an assembly of parts for supporting loads.
