Lesson 7: Exam Preparation

Question 1

What are the key topics to study for the exam?

Answer 1

1. Resultant force and equilibrium (LW01 - LW03).
2. Moments, couples, and distributed loads (LW02 - LW04).
3. Shear force and bending moment diagrams (LW04 - LW06).
4. Bending stress and strain calculations (LW06)

Question 2

What is the procedure to analyze a beam?

Answer 2

1. Draw Free Body Diagram (FBD).
2. Find support reactions using equilibrium equations.
3. Draw shear force (V-line) and bending moment (M-line) diagrams.
4. Calculate maximum bending stress using the flexure formula.

Question 3

What is the difference between statically determinate and indeterminate structures?

Answer 3

• Statically determinate: All support reactions can be found using only equilibrium equations.
• Statically indeterminate: Requires additional equations (compatibility conditions).
