1.5.1. Trusses

Try these first

1. 1.

   What is a truss?

   Hint

   Think about structures that require large spans.

2. 2.

   Name the two main types of trusses.

   Hint

   Consider their dimensional properties.

3. 3.

   What is the primary function of a truss?

   • To span small distances
   • To reduce the amount of material used
   • To distribute loads over large spans

   Hint

   Think about the purpose of structures in engineering.

4. 4.

   True or False: A planar truss is a three-dimensional structure.

   • True
   • False

   Hint

   Recall the definitions of planar and space trusses.

5. 5.

   Design a truss layout for a bridge spanning 60 feet. What geometrical shapes would you propose to maximize strength?

   Hint

   Consider the most efficient shape for spanning long distances.

6. 6.

   You have a truss with known loads. Calculate internal forces using the method of joints.

   Hint

   Use basic principles from static equilibrium to guide your calculations.
