4.1.1. Assumptions

Try these first

1. 1.

   What type of forces do cables primarily carry?

   Hint

   Think about how cables are used in construction.

2. 2.

   True or False: Trusses can only carry tensile forces.

   Hint

   Remember, trusses can manage both types of forces.

3. 3.

   What is the function of cables in structural applications?

   • They carry compression
   • They carry tension
   • They carry both

   Hint

   Think of how cables are used in bridges.

4. 4.

   True or False: Joints in trusses are assumed to be frictionless.

   • True
   • False

   Hint

   Recall the definition of a hinge.

5. 5.

   Given a truss with a compressive axial load applied inappropriately, analyze how this affects the overall stability using practical examples from construction.

   Hint

   Consider examples like poorly designed bridge supports.

6. 6.

   Compare the long-term performance of a Pratt truss versus a Howe truss in a heavy-load environment.

   Hint

   Evaluate the properties of the materials used over time.
