Purpose of an Inclined Plane Fill in the blanks below.
11. Purpose:
12. The inclined plane makes work easier by ______the amount of effort that must be applied to raise or lower a load.
13. To reduce the amount of effort needed to raise or lower an object in an inclined plane, the length of the slope should be ______. (extended or reduced)
Build and Modify Place a check in the boxes below as the team completes each step.
14. Build Rokenbok Inclined Plane
15. Test Inclined Plane - Step 1
16. Test Inclined Plane - Step 2
2 Build & Modify
Understanding Mechanical Advantage Fill in the blanks in the statements below.
17. Mechanical Advantage exists when the ______force of a machine is ______than the ______force that was applied to it.
18. For a machine to create mechanical advantage, it must trade increased time or ______for reduced effort.
Mechanical Advantage in an Inclined Plane Use the formula for calculating mechanical advantage to solve the Example 1 - Inclined Plane problems below.
19. Determine the mechanical advantage of the inclined plane in Example 1. (60cm) Mechanical Advantage:
Length of Slope Height of Rise Formula (120cm)
Mechanical = Slope Advantage Rise Example 2 - Inclined PlaneExample B
20. Determine the mechanical advantage of the inclined plane in Example 2. (60cm) Mechanical Advantage:
Length of Slope Height of Rise (180cm)
Modify Inclined Plane Place a check in the box below as the team completes each step.
21. Modify Rokenbok Inclined Plane from 2:1 to 3:1 Mechanical Advantage.
22. Teacher confirms modification is correct.

Sub-Challenge:
Sub-Challenge:
Review specifications.
2. Brainstorm Ideas & Solutions
Discuss design ideas.
Consider building components and cost.
3. Build A Prototype Build a working prototype of the design.
4. Test & Improve The Design
Test & improve the design for performance and consistency.
New challenge discovered:
Review grading rubric and design specifications.
Consider ways to reduce cost.
5. Explain The Design Prepare to demonstrate and present the design to others.
Review project grading rubric.
Explain any unique design features that were included.
Describe at least one new problem/challenge discovered during Step 4 (Test and Improve The Design) and how the team redesigned a new solution.
4 Design & Engineer
Challenge Evaluation When teams have completed the design & engineering challenge, it should be presented to the teacher and classmates for evaluation. Teams will be graded on the following criteria:
Specifications: Does the design meet all specifications as stated in the design brief?
Performance: How well does the design work? Does it function consistently?
Team Collaboration: How well did the team work together? Can each student descibe how they contributed?
Design Quality/Aesthetics: Is the design of high quality? Is it structurally strong, attractive, and well proportioned?
Material Cost: What was the total cost of the design? Was the team able to stay on or under budget?
Presentation: How well did the team communicate all aspects of the design to others?
