Classify each of the structures as statically determine inde

Classify each of the structures as statically determine, indeterminate, or stable. If indeterminate, specify the degree of indeterminacy.

Solution

a) This is a stable structure. This is indeterminate structure . Degree of indeterminacy = 2+2-3 = 1

b)This is a stable structure. This is indeterminate structure . Degree of indeterminacy = 2+2+1-3 = 2

c)This is a stable structure. This is determinate structure . Degree of indeterminacy = 3+1-3-1 = 0

d) This is a stable structure. This is indeterminate structure . Degree of indeterminacy = 3+3+1+1-3-1 = 4

e) This is a stable structure. This is indeterminate structure . Degree of indeterminacy = 2+2+1-3 = 2
