Project 3.2.5 Hydraulic Lift Design Rubric

Design

Topics / 4 points / 3 points / 2 points / 1 point
Brainstorming Sketch Ideas / Generates at least three viable ideas. Selects most appropriate concept and clearly justifies the choice using appropriate criteria. / Generates three concepts. Selects an appropriate concept and is somewhat able to justify the choice using marginally acceptable criteria. / Generates two concepts. Selects one using inadequate criteria. / Generates one concept.
Final Sketch / Uses appropriate symbols, is complete, correct, neatly done, and meets the design requirements. / Uses mostly appropriate symbols, is complete, neatly done, and meets the design requirements. / Uses several incorrect symbols, is complete, lacks neatness, and meets the design requirements. / Uses some correct symbols, is partially incomplete, and meets most design requirements.
Final Sketch Written Communication / Is properly detailed for effective communication including labels, descriptions, signatures, and dates. / Is marginally detailed for effective communication including labels, descriptions, signatures, and dates. / Lacks many details for effective communication including missing labels, descriptions, signatures, and dates. / Lacks most details for effective communication including missing labels, descriptions, signatures, and dates.
Design
Requirements / Fully meets design requirements. / Meets most design requirements and supports the design function. / Meets some requirements but not enough to support the design function. / Does not meet designrequirements.

Design
Requirements / Fully meets design requirements. / Meets most design requirements and supports the design function. / Meets some requirements but not enough to support the design function. / Does not meet designrequirements.
Quality / Well built with appropriate choices for materials. / Well built, but better material choices could have been made. / Built with flaws and better material choices could have been made. / Poorly built and poor material choices.
Functionality / Mechanisms function together consistently and accomplish the identified task. / Mechanisms function together most of the time and accomplish the identified task. / Mechanisms function together sometimes and do not always accomplish the identified task. / Mechanisms functions rarely and cannot accomplish the identified task.
Mechanical Advantage / Mechanical advantage is4 or better. / Mechanical advantage isbetween 3 and 4. / Mechanical advantage isbetween 2 and 3. / Mechanical advantage isless than 2.
