3.4.4. Problems

Try these first

1. 1.

   What is static determinacy in the context of truss analysis?

   Hint

   Think about what conditions must be met for a structure to be analyzed.

2. 2.

   Name the two types of internal forces in trusses.

   Hint

   Consider how these forces affect the structural integrity.

3. 3.

   What is the first step in analyzing a truss?

   • Check for static determinacy
   • Draw a free-body diagram
   • Assume member forces are tensile

   Hint

   What condition must the truss meet to ensure proper analysis?

4. 4.

   True or False: A negative member force indicates the member is in tension.

   • True
   • False

   Hint

   Consider what happens when your initial assumptions about direction are incorrect.

5. 5.

   Design a simple truss system to support a specific load. Specify the member sizes and materials to ensure it is statically determinate.

   Hint

   Refer to tension and compression requirements based on loading.

6. 6.

   Analyze a complex truss structure with a given load and calculate member forces using the method of joints. Discuss any assumptions necessary for your analysis.

   Hint

   Remember to draw free-body diagrams for each joint to visualize the components.
