Classify the frames shown in Figure 3.6 through Figure 3.8 as stable or unstable, determinate or indeterminate. If indeterminate, state the degree of indeterminacy.

Solutionr = 3, m = 3, c = 0, j = 43m+r > 3j+c12 = 12,The frame is statically determinate.

Solutionr = 6, m = 3, c = 1, j = 43m+r > 3j+c15 > 13The frame is statically indeterminate with 2°.

Solutionr = 4, m = 9, c = 0, j = 83m+r > 3j+c13 > 6The frame is statically indeterminate with 7° 0f indeterminacy.
