Classify the trusses in Figure P4.2 as stable or unstable. If
stable, indicate if determinate or indeterminate. If indeterminate,
indicate the degree.
a) Stable if (m+r>2j). Otherwise unstable.
m= number of members
r= number of reactions.
j= number of joints.
17+5>2*10 =22>20: Hence stable
Degree of indeterminacy = m+r-2j = 22-20 =2: Statically indeterminate to 2nd degree
b) Stable if (m+r>2j). Otherwise unstable.
m= number of members
r= number of reactions.
j= number of joints.
13+5=2*9 19=18: Hence stable
Degree of indeterminacy = m+r-2j = 19-18 =0: Statically determinate
c) Stable if (m+r>2j). Otherwise unstable.
m= number of members
r= number of reactions.
j= number of joints.
8+4=2*6 =12>12: Hence stable
Degree of indeterminacy = m+r-2j = 12-12=0: Statically determinate
d) Stable if (m+r>2j). Otherwise unstable.
m= number of members
r= number of reactions.
j= number of joints.
14+3>2*8 =17>16: Hence stable
Degree of indeterminacy = m+r-2j = 17-16 =1: Statically indeterminate to 1 degree

Classify each of the plane trusses shown in Fig. Q1.1 as unstable, statically determinate, or statically indeterminate. Explain your answer for each. If the truss is statically indeterminate, then determine the degree of static indeterminacy.
Classify each of the structures shown in Figure 1 as statically
determinate, statically indeterminate, stable or unstable. If
indeterminate, specify the degree of indeterminacy. The supports or
connections are to be assumed as stated.
