3.2. Assumptions for Analysis of Trusses

Try these first

1. 1.

   What type of joints are used in plane trusses?

   Hint

   Think about how members connect.

2. 2.

   Where do we apply loads in a truss?

   Hint

   Consider the points of contact.

3. 3.

   Where are loads applied on a truss?

   • At the middle of members
   • At the joints
   • Along the length of members

   Hint

   Think about the connection points.

4. 4.

   True or False: Truss members can be connected at points other than their ends.

   • True
   • False

   Hint

   Focus on how members interact.

5. 5.

   Consider a theoretical truss where members are connected with adhesive rather than frictionless joints. Discuss how this could alter the static analysis of loads.

   Hint

   Think about how sticky connections could change interactions.

6. 6.

   If a truss has a misalignment in mentral connections causing two members to be slightly out of place, theorize the impact this may have on load distribution and member tension.

   Hint

   Visualize how weight would shift in a real-world structure.
