Use all phases and all parts of the paddle. Some sections will include detail, others will be just a cursory discussion of the issues associated with a particular phase of the stroke.
Be sure to use equation editor for your equations. Use proper reference format. Include your charts with lines marked on them and proper screening of candidate materials.
Format, use equation editor and format on web page 1 pt.
Objectives and function 1 pt.
Sections of stroke define objectives 2 pt.
Loading for each stage of stroke with FBD 2 pt.
Objective function for each sub system in paddle 1 pt.
Line on chart for functions 1 pt.
Manufacturing issues discussed 1 pt.
You will be assigned one of four materials which you will research using the metals handbook and other references as required. The four materials that will be assigned to the class are Ti-6Al-6V-2Sn, M-2 Tool Steel, 17-4 Precipitation Hardened Stainless Steel and 5086-H32 Aluminum.
The sections in the report are:
Composition and tolerances
TTT Diagram (if applicable, if not explain why)
Possible Heat treat
Risks to utilization, temperature, corrosion
Testing, Modulus, Strength and Toughness
Due March 22nd 2005, at 4:00 pm.
We will discuss final questions during the class period. DO NOT WAIT UNTIL THE LAST MINUTE. THIS IS A RESEARCH PROJECT.
The initial offer of an idea will occur on March 31, 2004, at that time you need to have an idea, and a group to work with. I will respond to the idea during class time.

Separate your project into components which are suitable for drawing a free body diagram. These will then be the basis of the material selection.
The project will be graded based on the following basis (click here)
