Bicycle Frame Excavator Bucket Scoop: Assessment Criteria

This document provides assessment criteria for evaluating a report on selecting appropriate materials for redesigning bicycle frames or excavator buckets. Students must 1) select materials based on required properties to meet component needs, 2) devise a testing schedule for the new materials, and 3) discuss how material selection may differ for different production scenarios. The report will be evaluated based on comprehensively addressing the tasks and presenting findings clearly with proper formatting, diagrams, justification, and references. Selection of novel materials requires demonstrating understanding of material properties, treatments, and how testing relates to end use conditions.

Assessment Criteria

1.1 To correctly determine the material properties required to satisfy a particular component
requirement.
1.2 To be able to clearly and satisfactory communicate in writing engineering reasons for the
material choices made and understanding of future developments.

Assessment Module Weighting – 50%

Learning outcomes to be assessed

(C) Appreciate the differences in the basic mechanical properties of materials and basic strengthening
mechanisms for metals.

(D) Make informed decisions on the selection of materials.

Background information

You should choose one of the following components to complete your task

 Bicycle frame (see Fig.1 below)


 Excavator bucket scoop (see Fig. 2 below)

Task

a) You are working on the redesign of your chosen component, your particular task is to specify
the appropriate material for the new component, however you are working for a competitor
company to the existing manufacturer and the ethos of the redesign is for weight reduction in
all components to improve on performance.
b) In conjunction with the research department, in light of the fact you have specified a novel
material for the manufacture of the component; you are also tasked with devising a testing
schedule in order to ensure safety and performance of the new material before the
components are manufactured.
c) You have been asked by the board how your material selection might differ if you were
producing the same component for

a. A high-end small volume product


b. An inexpensive mass-produced product where lifespan is less important
c. An increase in load

All of your findings need to be summarised in a report (use of the material selection template report
and use of diagrams and charts is actively encouraged).

Assessment Strategy

Task a – 40% Task b – 30% Task c – 20% Presentation – 10%
