Links
• Help connect two or more parts of a technical object
• Linking is the basic mechanical function provided by any component that links an object’s parts or parts of different objects
• A linking component is one that has the basic mechanical function of linking

Words To Know:
1. Translational:– Back and forth movement– It CAN move back and forth:– It CANNOT move back and forth:
2. Rotational– Rotating movement– It CAN rotate:– It CANNOT rotate:

Fixed link(a.k.a. embedded link)
• There is no movement between linked parts
Screen & case

Sliding link
• The guided part can undergo translational motion along one axis
Drawer Slides

Sliding rotating link(a.k.a. sliding pivot)
• The guided part can undergo rotational and translational motion on the same axis, separately (independently)
Seat post & seat tube

Spherical link(a.k.a. ball joint)
• The guided part can undergo rotational motion in many directions
Joystick

Helical link• The guided part can undergo helical motion. Unlike
sliding-rotating link, during helical motion a part must rotate AND translate (move back/ forth) at the same time)
Nut and bolt

Support Base Link
• Can undergo movement parallel to the support base only
• Computer Mouse
