The following data are taken from Grainger
Catalog (http://www.grainger.com/Grainger/start.jsp).
·
The wrench has these major components:
handle, ratchet, drive, switch, and cover. This list is not inclusive. ·
Design a similar (not necessarily identical)
ratchet wrench. ·
Assume that loads are static (use the
worst-case scenario). ·
Use an appropriate human factors handbook
to obtain suitable dimensions for the wrench. · You are to choose materials and dimensions such that the machine will not fail due to any possible combinations of stresses. ·
Use the
rapid prototyping machine to create a 1:2
scale model of your design. Note: You may need to disassemble a wrench to better understand it.
