7.4. Howe truss

Try these first

1. 1.

   What are the two main types of members found in a Howe truss?

   Hint

   Think about the orientation of the members.

2. 2.

   Define compression in the context of trusses.

   Hint

   Consider the opposite of tension.

3. 3.

   What type of force do vertical members in a Howe truss primarily resist?

   • Compression
   • Tension
   • Bending

   Hint

   Think of how they interact with the loads.

4. 4.

   True or False: The diagonal members in a Howe truss primarily experience compressive forces.

   • True
   • False

   Hint

   Consider the orientation of forces in the truss.

5. 5.

   Design a simple Howe truss for a pedestrian bridge. Ensure it can carry a specific load with materials chosen for both weight and strength.

   Hint

   Consider the load factor, safety, and aesthetic value in your design.

6. 6.

   Given a Howe truss with two known loads, calculate the internal forces in both diagonal members using the Method of Joints.

   Hint

   Use clear free-body diagrams to visualize forces acting on each joint.
