s an easy divided by the number of panels in the rule for determining the strains by this me- truss gives the maximum strain in the thod for any tie or post. Take the num- ber of panels in both systems (10 in the given members from rolling load. A counterbrace is needed in the posi- present case)… … sec. 6 (to' £ — 0.5 w). The heavy lined use either the method by series, or the tie which it crosses is susceptible of re- method by increments, which agree very ceiving a compressive strain of equal nearly in their results.
