Jessop, C. M. (Charles Minshall), 1861-1939 · London, New York, G. Bell and Sons; [etc.] · leaf 245
amwe see that the force m the pin Q is from Q towards 8,or the bar pulls the pin in, hence the pin pulls the bar out,thus Q8 is a tie. * That is, we can find their magnitudes by actually measuring the linesae, he &a. These lines represent the forces in the scale in which ah repre-sents W. 15… … The lines db and be are drawn to represent W and Wrespectively. Any pole 0 is taken and joined to a, b and c; KL, LMand MN are drawn parallel to Oc, Oh and Oa, then as before,a line Od drawn parallel to KN will meet ah in d so that cdand da represent the forces CD and DA, Through a and h, af and hf…
