Not long ago I was given a reference that might prove very helpful. Since I don’t have subscriptions to all of the great materials/periodicals out there and I am not near a large university with and ergo school, where can I find a reference online? It was Article: Estimation of hand force in ergonomic job evaluations, S. Bao & B Silverstien, Ergonomics, Vol. 48, No. 3, 22 February 2005, 288-301. Thanks for your tips and comments.
