  1. Mechanisms, Levers & Linkages GCSE Graphic Products

  2. The principles of simple mechanisms Learning Objectives By the end of this lesson you will have developed a knowledge and understanding of: • the principles of simple mechanisms and identify the relevant components and features • levers and linkages.

  3. The principles of simple mechanisms • A mechanism creates movement within a product. • There will be occasions when the graphic designer needs to include a mechanism in a product, whether it be a board game or a moving sign.

  4. Movement

  5. The lever • The lever is the simplest of mechanism. • A lever is a device that pivots around a point called the fulcrum. • When a force is applied to one side, the other side moves in the opposite direction. • By positioning the fulcrum the outputting force can be magnified, or diminished. • The speed and distance of the movement can also be magnified, or diminished.

  6. Types of lever Levers can be categorised as one of three types:

  7. Linkages • A linkage can act as a lever. • In most cases it transfers one mechanical motion to another. • A linkage is often used to connect other mechanical devices such as cams to levers or to cranks – or vice versa. • A simple linkage will see a lever attached to a lever.

  8. Types of linkages • Linkage fixed pivots • Linkage brings about change in direction and movement

  9. Types of linkages • Linkage with several moveable parts • Components that can be used for pivots

  10. Key terms • Lever – a rigid bar that can rotate around a fixed pivot called a fulcrum. • Linkage – a mechanism involving two or more levers. • Mechanism – creates movement. • Pivot – a point of rotation.

  11. Task • Make the different types of linkage
