distance from each other equal to a helical interval, andequally distant from m,v. If we now develop the portionof the cylindrical surface, included between the cutting-planes, on the tan- gent plane, the sur-face of the cylinderwill become a rectan-gle whose base A Eis equal to 2*7*, andwhose… … power andresistance intocomponents; draw the normal mlv L, and resolve Q and Fx as beforestated. Since Q = mlv K is perpendicular to A E, andLmIV perpendicular to A B, the angles LmlvKand EABare equal; also, since Ft = Imlv is perpendicular to BE,the angles Imlv L and ABE are equal, and the…
