**The Howe Bridge truss is subjected to the loading shown**

The Howe Bridge truss is subjected to the loading shown. Determine the force in members DE, DH, and IH, and state if the members are in tension or compression. Given F1 = 30 kN, F2 = 20 kN, F3 = 20 kN, F4 = 40 kN, a = 4 m, and b = 4 m

2
**The Pratt Bridge truss is subjected to the loading shown**

The Pratt Bridge truss is subjected to the loading shown. Determine the force in members LK, LD, and CD, and state if the members are in tension or compression. Given F1 = 50 kN, F2 = 50 kN, F3 = 50 kN, a = 4 m, and b = 3 m

3
**The roof truss supports the vertical loading**

The roof truss supports the vertical loading. Determine the force in members BC, BK, and LK, and state if the members are in tension or compression. Given F1 = 4 kN, F2 = 8 kN, a = 2 m, and b = 3 m

4
Determine the force in members CD, CJ, and KJ of the truss which serves to support the deck of a bridge. State if these members are in tension or compression. Given F1 = 4000 lb, F2 = 8000 lb, F3 = 5000 lb, a = 9 ft, and b = 12 ft
