Demonstrate understanding of basic concepts related to machines
This standard is about understanding how machines work and the basic building blocks that make them do what they do. You need to explain why machines use parts like levers, screws, gears, and bearings, and describe the advantages and disadvantages of different power systems (like pneumatic or hydraulic). It's about understanding the "why" and "how" behind machine design, not just naming parts.
You can explain the purpose of levers, screws, inclined planes, and mechanical components; compare pneumatic vs hydraulic systems; and describe what mechanical advantage and motion a machine provides.
You can explain HOW a machine actually provides its mechanical advantage and motion by linking the components together—not just what it does, but the mechanism behind it.
You can discuss WHY specific levers, screws, inclined planes, and mechanical components were selected for a particular machine to achieve its mechanical advantage and motion—you understand the design decisions.
