With regards to the testing of industrial safety helmets (hard hats), i am trying to get information on the testing procedure as outlined by ANSI Z89.1 2003.
I can't seem to find the actual details of the requirements or test criteria. What i need to know is the exact values of the maximum...
With regards to mountain bike designs, can anyone tell me how the actual forces due to rider weight and pedaling are isolated from the actual forces on the rear shock? What are the advantages of the rear suspension designed like this?
