1.5. Types of Structures

Try these first

1. 1.

   Define a truss.

   Hint

   Think about what shapes are used in construction for stability.

2. 2.

   What type of load do cables primarily resist?

   Hint

   Consider the flexibility of cables.

3. 3.

   What do trusses primarily use to provide strength?

   • Curved designs
   • Triangular shapes
   • Square frames

   Hint

   What geometric shape is known for its strength?

4. 4.

   True or False: Cables can only support compressive loads.

   • True
   • False

   Hint

   What happens with tension in a cable?

5. 5.

   Design a simple bridge using trusses and calculate the load-bearing capacity, considering forces applied and materials available.

   Hint

   Focus on the arrangement of triangular shapes to balance forces.

6. 6.

   Critically discuss the implications of choosing cables over arches in a specific bridge design scenario, considering factors such as load, span, and materials.

   Hint

   Consider the advantages of flexibility versus rigidity in supporting loads.
