For the truss systems shown determine they are stable/properly-constrained or
unstable/improperly-constrained. If stable, identify whether they are externally determinate or
indeterminate (both overall and externally); if indeterminate, make sure to indicate the degree of
indeterminacy (again, separating overall and external conditions).

(a) Number of members: m=22 Number of unknown reactions: r=3 Number of joints: j=13 m+r=22+3=252j=2×13=26 Therefore m+r<2j i.e., 25<26 Hence it is uns
