Part A - Determining the forces in three
specified members of the truss
Determine the forces in members CD, DH, and
GH.
Express the magnitudes of the forces in pounds to three
significant figures. Separate your answers with commas.

3. A 64 lb weight stretches a spring 4 ft in equilibrium. The weight is initially displaced 6 inches above equilibrium and given a downward velocity of 6 ft/sec. Find its displacement for t > 0 if the medium resists the motion with a force equal to 3 times the speed in ft/sec (that is, the damping constant c=3). Note that there is no external force in this case.
3* Question #2 (5 pts): In the figure at right, replace the forces and couple acting on the structural member shown with an equivalent force-couple system at point G. Use the following values: Fi -100 lb, F 90 lb, F-120 lb, and C- 200 lb-ft.

l Truss A truss is a structure that typically consists of 1. All straight members 2. connected together with pin joints 3. connected only at the ends of the members 4. and all external forces (loads&reactions) must be applied only at the joints. The weights of the members may be neglected. The basic building block of a truss is a triangle. Large...
