Mechanical Technology Grade 12 NSC Exam Topics and Structure Guide Syllabus

Mechanical Technology Grade 12 NSC Exam Topics and Structure Guide Syllabus The Grade 12 NSC exam for Mechanical Technology is designed to assess students’ understanding of key concepts, their ability to apply theoretical knowledge to practical situations, and their problem-solving skills. The exam typically consists of two components: a theory paper and a practical assessment.

Exam Structure: Mechanical Technology Grade 12

For Grades 10, 11 and 12, the three-hour end-of-year examination in Mechanical Technology (200 marks) comprises 50% of a learner’s total mark. All question papers set by the teacher throughout the year, including the November paper must be scrutinized by the head of department at the school and approved by the Mechanical Technology facilitator for the district. This is done to ensure that the prescribed weightings are adhered to by the teacher.

In the Grade 12 examination only Grade 12 content will be assessed. However, prior knowledge from Grades 10-11 may be necessary to interpret and answer some of the questions.

Theory Paper

The theory paper forms a significant portion of the exam and covers a wide range of topics related to mechanical engineering. These topics may include:

1. Engineering Drawing:
   • Orthographic projection
   • Isometric drawing
   • Sectional views
   • Dimensioning and tolerances
2. Mechanical Systems:
   • Study of gears, pulleys, and other mechanical components
   • Mechanical advantage and efficiency
   • Transmission systems
3. Manufacturing Processes:
   • Casting, forging, and machining processes
   • Material properties and selection
   • Quality control and inspection techniques
4. Mechanical Principles and Laws:
   • Newton’s laws of motion
   • Work, energy, and power
   • Friction and its effects
   • Stress, strain, and deformation
5. Safety and Maintenance:
   • Workplace safety practices
   • Maintenance schedules and procedures
   • Hazard identification and risk assessment

It’s essential for students to thoroughly revise each topic, understand the underlying principles, and practice solving related problems to perform well in the theory paper.

Practical Assessment

In addition to the theory paper, students are required to complete a practical assessment that demonstrates their ability to apply theoretical knowledge in real-world scenarios. The practical assessment may involve:

1. Design and Fabrication:
   • Designing and building a mechanical system or component based on given specifications
   • Selecting appropriate materials and manufacturing processes
   • Assembling and testing the final product
2. Problem-solving Tasks:
   • Identifying and diagnosing mechanical faults or issues
   • Implementing corrective measures
   • Documenting the problem-solving process
3. Experimental Work:
   • Conducting experiments to verify mechanical principles or laws
   • Collecting and analyzing data
   • Drawing conclusions and making recommendations
