{ D { C 5) The box truss shown in the figure is loaded by three vertical forces acting at joints A, B, and E. All horizontal and vertical bars in the truss are of length 2m. Find the forces in members AB, AC, and DC. B E 20 kN 50 kN 20 kN

Determine the force in each member of the truss ABCD. The truss supports a vertical load of P1=1.50kN at Point B and a horzontal load P2=2.25kN at Point D. The truss is supported by a pin connection at Point C and a roller at Point A and the truss dimensions are L1=3.6m, L2=3.6m, and L3=4.8m. State whether the members are in tension or compression.

From the given cantilever truss which is supported by a hinge at A and a roller at B, determine the forces at bar 3. 10N1 EQ 2.4m 2.4m + F 0 8 2.4m 1 2.4m 2m

For the following truss structure: (a) Identify the null member(s) and the null joint(s) (if there is any); (b) Determine the support reactions at C and G; (c) Determine the magnitude and nature of the axial force in members indicated by “×”.
