Definitions p. 207

Components are… The parts or fluids that have a mechanical function

Components

A basic mechanical function… Is the role played by a component or a group of components in the function or assembly of a technical object

Screw > bolt ?

Guiding… Is the basic mechanical function of any component that controls the motion of one or several moving parts

A guide is… A component that has the basic mechanical function of guiding

Axle ?

A link… Helps 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

A linking component… Is one that has the basic mechanical function of linking

Veneer + Glue = skate board

Main Types of Guides p. 207

Rotational guide This kind of guide only allows the rotational motion of moving parts

Bike Axle

Translational guide This kind of guide only allows the translational motion of moving parts

Bike suspension

Characteristics of links p. 208

1st Characteristic pair Direct Indirect

Direct A direct link exists when two parts can hold together without requiring a linking component

Cell Phone > Case

Indirect An indirect link exists when the parts require a linking component to hold them together

? Arm > Frame

2nd Characteristic pair Rigid Flexible

Rigid A rigid link exists when the surfaces of the linked parts or the linking component are rigid

Base > monitor

Flexible A flexible link exists when the surface of the linked parts or the linking component can be deformed

Pages > spine

3rd Characteristic pair Removable Non-removable

Removable A removable link exists when linked parts can be separated without damaging them

Laces > eyelets

Non-removable A non-removable link exists when separating the linked parts damages them or the linking component

? Sole > upper

Complete link There is a complete link when there is no movement between linked parts

Top > bottom

Partial There is a partial link when at least one part is capable of motion with respect to the other

Cap > pen
