EXERCISE 1: Fault Diagnosis

During testing of a prototype system, a mechanical assembly driven by a small electric motor fails after only a few minutes of operation.

Observed symptoms:

• The motor becomes very hot
• The mechanism occasionally jams or stalls
• A faint grinding noise can be heard during operation

You have access to the prototype, the test rig, and standard workshop tools.

Task

Describe how you would approach diagnosing the problem.

Your answer should include:

1. The possible causes you would investigate
2. The checks or measurements you would perform
3. How you would isolate the root cause
4. How you would document and communicate the issue to the engineering team

Please limit your response to approximately 300 words.

EXERCISE 2: Prototype Build Planning

You are asked to assemble a prototype mechanical system consisting of:

• a motor
• a gearbox
• a mounting frame
• a small electronic control module

The components have arrived from different suppliers and must be assembled into a working prototype for testing.

Task

Describe how you would approach this build.

Your answer should include:

1. The checks you would perform before starting the build
2. How you would organise the assembly process
3. What you would do to ensure build quality and reliability
4. How you would record the build for future reference

Please limit your response to approximately 300 words.

EXERCISE 3: Working at Pace
