Worked Solution & Example Answer:2.1 Which TWO safety precautions must be observed when working with a coil spring compressor? 2.2 State THREE safety precautions that should be observed before pressing a bearing from a shaft using a hydraulic press - NSC Mechanical Technology Automotive - Question 2 - 2017 - Paper 1

Step 1

Which TWO safety precautions must be observed when working with a coil spring compressor?

96%

114 rated

Answer

Ensure that the diameter of the compressor bolts can withstand the pressure exerted by the coil spring.
Do not exceed the maximum pressure limits specified for the compressor.

Step 2

State THREE safety precautions that should be observed before pressing a bearing from a shaft using a hydraulic press.

99%

104 rated

Answer

Take notice of the predetermined pressure of the hydraulic press to avoid excessive force.
Ensure that the pressure gauge is functioning properly to accurately monitor the force applied.
Make sure the work piece is securely positioned on a rigid platform that is square with the cylinder of the press.

Step 3

State TWO safety precautions to be considered when using the beam-bending tester.

96%

101 rated

Answer

Ensure the beam is firmly clamped to the backboard to prevent movement during testing.
Avoid placing plastic beams in the tester for prolonged periods to prevent material distortion.

Step 4

Name ONE distinct safety precaution when using EACH of the following items of testing equipment:

98%

120 rated

Answer

2.4.1 Brinell tester: The tester must be mounted securely on a stable worktable. 2.4.2 Gear and bearing puller: Ensure the puller is set at a 90° angle to the work piece before attempting to pull. 2.4.3 Torsion tester: Obtain and verify the specifications for the materials and rods to be tested.
