Purpose: Tolearnmoreaboutthemostwidelyusedtransportationvehicleintheworldhowit functions,howitevolved,andhowtokeepyoursinbettercondition. Acknowledgement: This module uses as its inspiration materials from ME99: Mechanical Dissection, a 10-week course at Stanford University developed by Sheri Sheppard under the auspices of the NSF Synthesis coalition. Physical principles involved: Static torque and force analysis, power transmission Mechanisms involved: Mechanical transmissions (crank, roller chains, sprockets), ball bearings, tubular frames, brakes, free-wheel, shifter (derailleur) Activities: Dissection, sketching, CAD drawing, force/power analysis Required tools: Basic toolbox, parts bin, lubricants (30W oil, Teflon lube, white lithium grease), cleaning solution (kerosene), special bike tools: Crank Spanner Cone Wrenches (9,11,13,15 mm) Freewheel removal tool (3 possible types) Chain tool Spoke Wrench
Dissection Deliverables: 1. Assembled, working, well-adjusted bicycle; 2. Computer generated assembly drawing of rear hub unit; and 3. Detailed journal record of activities including: a) details of all procedures followed and answers to all questions, and b) sketches of parts and assemblies and all other pertinent information.
