U3d-L4
• Machines are artifacts that transmit or change the application of power, force, or motion.
• What is an artifact?– something created by humans usually for a practical
purpose.
• Machines can be simple or complex– Complex machines are comprised of…. Simple Machines

U3d-L4
• Simple machines work on 2 basic principles:
LEVER
INCLINED PLANE
Principle: a law of nature underlying the working of an artificial device

U3d-L4
• 3 Categories of simple machines based on the principle of the LEVER:
LEVER
Lever Wheel and Axle
Pulley

• Lever Arm • Fulcrum• Applied Force• Load• 3 different Classes of levers:
U3d-L4
LEVER

Which is 1st class?
U3d-L4
• 1st class:– The fulcrum is between the load and the effort force
LEVER

Which is 2nd class?
U3d-L4
• 2nd class:– The load is between the effort and the fulcrum
LEVER

U3d-L4
• Identify and sketch 3 common mechanical devices (not discussed in class during this lesson) that exhibit characteristics of the 3 classes of lever.
• For example:
