WebNär jämställdheten uppfylls i Grashofs formel, är vi i det begränsande fallet där summan av den kortaste stapeln med de längsta staplarna är lika med summan av de andra två. I detta fall kan mekanismen anta en konfiguration i vilken de fyra staplarna är inriktade. Och det är i detta läge, de icke-fasta lederna kan likgiltigt gå en ...
