| Abstract: | The',fundamental equations for analysis-of a straight slender, rod which deform-at largo deflections of order of several times-of the dimension of the cross section of the rody are .darivd bj. using convocted coordinate system. In accordance with ihe practice of oil drilling. :-:n effective rne-hod of thr:e dimensional stati" analy-sis of bottom-hole assemblies is simply desibe/l. Errors in reference [8j are poifl'ted out |
