3.3.2. Examples

Try these first

1. 1.

   What is the method used for truss analysis called?

   Hint

   It involves analyzing forces at the joints.

2. 2.

   What do tensile forces do in a truss member?

   Hint

   Remember, tensile forces extend the member.

3. 3.

   What must be checked first in truss analysis?

   • Member Forces
   • Static Determinacy
   • Free-Body Diagrams

   Hint

   Consider what ensures we can proceed with the method of joints.

4. 4.

   True or False: A negative force indicates a member is in tension.

   • True
   • False

   Hint

   Remember the definitions of tension and compression.

5. 5.

   Analyze a truss with varied inclined loads and determine forces in each member.

   Hint

   Focus on each joint separately and remember, use assumptions wisely.

6. 6.

   Given a truss design failure, hypothesize potential causes based on member forces.

   Hint

   Consider common failure points in structural engineering.
