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.

Step 1

Apply the sign conventions for calculating reactions, forces and moments using the three equations of equilibrium as shown below.

• The forces acting towards right side as positive and the forces acting towards left side as negative.
• The upward force as positive and the downward force as negative.
• The clockwise moment as negative and the counter clockwise moment as positive.

Show the free body diagram of the truss as shown in Figure 1.

Step 2

Apply the Equations of Equilibirium as follows:

Step 3

Calculate the value of the...
