4.3.2. Examples

Try these first

1. 1.

   What is a free-body diagram and why is it necessary?

   Hint

   Think about what needs to be included in such diagrams.

2. 2.

   Can you name one method to calculate support reactions in a frame?

   Hint

   Consider what forces act in static systems.

3. 3.

   What is the first step to analyze a statically determinate frame?

   • Check for static determinacy
   • Draw the shear diagram
   • Calculate support reactions

   Hint

   Think about whether equilibrium can be fully established.

4. 4.

   True or False: The moment shown on the tension side of the frame is preferred for concrete design.

   • True
   • False

   Hint

   Recall the standard conventions used in structural analysis.

5. 5.

   A frame has multiple loading points. Describe the process you would take to resolve all forces and moments systematically.

   Hint

   Components and sections can simplify complex structures—use sections wisely.

6. 6.

   Construct both shear and bending moment diagrams for a member under uniform loading followed by a point load at mid-length.

   Hint

   Start from one end and integrate the effect of loads incrementally.
