Step 1
Step 2
State THREE safety precautions that should be observed before pressing a bearing from a shaft using a hydraulic press.
Answer
-
Take notice of the predetermined pressure of the hydraulic press to avoid exceeding limits.
-
Ensure the pressure gauge is in good working order to monitor the pressure effectively.
-
Check for oil leaks in the hydraulic system to prevent hazards.
Step 3
State TWO safety precautions to be considered when using the beam-bending tester.
Answer
-
Ensure the beam's stability by clamping it securely to the backboard to prevent any movement.
-
Avoid placing plastic beams loaded for long periods, as they may deform due to gradual weight application.
Step 4
Name ONE distinct safety precaution when using EACH of the following items of testing equipment:
Answer
2.4.1 Brinell tester:
- The tester must be mounted rigidly on a worktable to ensure stability.
2.4.2 Gear and bearing puller:
- Ensure that the puller is at a 90° angle to the workpiece before attempting to pull.
2.4.3 Torsion tester:
- Obtain specifications of the different materials and the size of rods you wish to test prior to use.
