NOTE

ENGINEERING DESIGNS AND WORKING DRAWINGS

The engineering design process is a systematic approach used by engineers to solve problems and create solutions. It typically involves the following steps:

  1. Identify the Problem: Clearly define the issue or opportunity that needs addressing.
  2. Research and Gather Information: Gather relevant data and information about the problem, including constraints and requirements.
  3. Brainstorm Solutions: Generate a variety of possible solutions, considering different approaches and technologies.
  4. Evaluate Solutions: Assess each potential solution based on criteria such as feasibility, effectiveness, cost, and impact.
  5. Select a Solution: Choose the most promising solution or combination of solutions.
  6. Develop the Solution: Create detailed designs and plans for implementing the chosen solution.
  7. Prototype and Test: Build a prototype or model of the solution and test it to ensure it meets the requirements and functions as intended.
  8. Iterate and Refine: Based on test results and feedback, make improvements to the design and iterate the process as needed.
  9. Implement the Solution: Put the final design into action, whether it's a product, system, or process.

Working drawings

working drawings are the scale drawings of the building work used by the builders of the project. Working drawings include all kinds of information, such as electrical and mechanical drawings, scaling, civil and structural work, and any other relevant information to the project.

EVALUATION: 1. Discuss the processes involved in carrying out an engineering design.

  1. Identify the important Components of a working drawing.

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
