Abstract
Free Body Diagram (FBD) is one of the most important concepts in Engineering Mechanics because it forms the foundation for solving force, equilibrium, friction, truss, and motion problems. However, many first-year engineering students commit errors while drawing FBDs due to weak conceptual understanding and lack of practice. This study investigates common mistakes made by first-year engineering students in drawing Free Body Diagrams. A sample group of students was tested using mechanics problems involving blocks, beams, ladders, pulleys, and trusses. Errors were categorized and analyzed statistically. The results indicate that incorrect force direction, missing reaction forces, unnecessary forces, and poor axis selection are the most frequent mistakes. The paper recommends improved teaching methods, visual tools, and regular practice to strengthen student understanding.

Conclusion
Free Body Diagram errors are common among first-year engineering students and directly affect mechanics problem-solving ability. Missing reactions, wrong friction direction, and extra forces are the most frequent mistakes.
The study recommends activity-based teaching, visual tools, and repeated practice to strengthen conceptual understanding.
Correct FBD learning will improve performance in Engineering Mechanics and later core engineering subjects.
