Yan, “Rigid Body Guidance for Planar Five Bar Linkages for Five Precision Positions”, Journal of Chinese Society of Mechanical Engineers, Vol. I am hopeful of discovering something in matlab data that makes by their Figure 3. ”Phil;These were discussions among me and two Chinese scientists and that they were resolved, as evidenced by matlab paper in Journal of Geophysical Research. It was about confusion over different regions of China. REPLY:Gee Phil, if you were perplexed, one would think that you just would ask them for clarification. Instead you said you were looking for engineering way to argue that their results were wrong and couldn’t think of engineering way to do it. Yes, that seems like confusion to me. WAEC 2005.
