28 ページ - AC and BC represent bars, which are connected at A and B by bolts to a wall piece, and at C by bolt to each other. A weight P acts on the bolt C, and we want to ascertain the strain in the two bars. Firstly We have to apply two rectangular axes through (7, and because AC is horizontal, and CP vertical, we take these directions as the axes.
30 ページ - For axes we always take one horizontal and one vertical line, and because we have three free connection-points, 1, 2, and 4, we can form six equations, by which we are able to ascertain all the six strains at once. For point 2 we have the same equations as in the previous example, by introducing...

32 ページ - We have still to ascertain the strains 8 ol and 8 13 , which we are able to do by the equations of point (1), after having altered them in the same way : 8 <- ^oi 8 P a U I . AJ la - J.
29 ページ - By this all bars are determined in length and position, and we can proceed to resolve the forces. For axes we always take one horizontal and one vertical line, and because...
6 ページ - That each bar is exposed to tension and compression only in the direction of its longitudinal axis, which is the most favorable condition possible.
