Classify the following truss as statically determinate (SD), statically indeterminate (SI), stable, or unstable. If statically indeterminate, determine the degree of indeterminacy. If unstable, explain why. B m +R- 2J = SD SI O NA Only when SI is selected, then answer SI = Stable Unstable, because a member is missing between A and B Unstable, because there is an internal collapse mechanism

The static indeterminacy of the structure shown below is G F Hinge. С E B (A)Unstable (B) Stable, determinate (C) Stable, 5th degree indeterminate (D)Stable, 3rd degree indeterminate

All bars in the truss have the same cross section and material properties. Find the total change in length of the cord A-B-C, and the stress at point p in the coordinate system given. ⁹00 lb AABC = σ= in ksi A = 0.64 in² E 30000 ksi V = 0.29 point p A Y 800 lb. 5 ft B 11200 lb 5 ft C 800 lb F 4 ft 4 ft

For the steel truss (E = 29 x 106 psi) and loading shown, determine the deformations members AB, BC, BE, DE and DF , knowing that their cross-sectional areas are 2 in2.

14. A pin-connected structure consists of a rigid beam ABCD and two supporting bars. Bar (1) is an aluminum alloy [E = 70 GPa] with a cross-sectional area of A₁ = 2,400 mm². Bar (2) is a bronze alloy [E = 100 GPa] with a cross-sectional area of A2 = 6,000 mm². All bars are unstressed before the load P is applied.

29. A truss is subjected to loading as shown. Determine the reactions at the supports and all the forces acting on each member and their behavior

1) The truss (containing 12 pin joints, A, B, C, ... L) shown in the figure is simply supported at points H and L that are 4 meters apart. Angles A between different truss members are either 90° or 45° and the member lengths are either 1 m or m.
