Final answer:
To determine the force in each member of the truss and whether they are in tension or compression, we need to analyze the forces acting on the truss and use the method of joints to apply the equilibrium equations to each joint.
Step-by-step explanation:
To determine the force in each member of the truss and whether they are in tension or compression, we need to analyze the forces acting on the truss. Since all members are pin connected, we can assume they are in static equilibrium. By using the method of joints, we can apply the equilibrium equations to each joint to determine the forces in the members.
For each joint, sum the forces in the x and y directions to find the unknown forces in the members. If a member has a positive force, it is in tension, and if it has a negative force, it is in compression.
By following this process for each joint in the truss, we can find the forces in all the members and determine if they are in tension or compression.
