Links in Technical Objects

Links A link refers to the connection between two components of an object. There are different characteristics of this connection that we need to think about.

Criteria 1: Direct or Indirect Direct: The link does not require a linking component.

Criteria 1: Direct or Indirect Direct: The link does not require a linking component. Indirect: The link does require a linking component (ex: screw, glue, etc)

Criteria 2: Rigid or Flexible Rigid: The linking is not flexible (it cannot be bent out of shape).

Criteria 2: Rigid or Flexible Rigid: The linking is not flexible (it cannot be bent out of shape). Flexible: The link can be deformed when used and has the ability to return to its initial position.

Criteria 3: Removable or Permanent? Removable: You can separate the two linked items without breaking the object.

Criteria 3: Removable or Permanent? Removable: You can separate the two linked items without breaking the object. Permanent: You cannot separate the two linked items without breaking the object.

Criteria 4: Complete or Partial? Complete: The link does not allow the two connecting parts to be moving independently.

Criteria 4: Complete or Partial? Complete: The link does not allow the two connecting parts to be moving independently. Partial: The two connecting parts can move independently.

Guiding controls the motion of an object Guiding controls the motion of an object. There are 3 types of guides and movements:

1. Translational: This allows translational movement (up-and-down, or left-to-right movement)

2. Rotational: This allows rotational movement (spinning around something).

3. Helical: This type of guide allows translational motion of a moving part while it rotates (combination of translational and rotational).

Work Period Finish up your helmet lab. It will be collected on Thursday. Links and Guides practice: Workbook page 188-189 (#1-2, 4-7). This is not for homework yet, but it will be eventually.
