Final answer:
The recommended method of removing an external bending spring is not provided, but general safety practice involves carefully decompressing the spring's tension. Similar to how mechanics use a pipe over a wrench handle to increase leverage for a tight bolt, proper tools and careful handling are critical for safely dealing with springs.
Step-by-step explanation:
The recommended method of removing an external bending spring is not explicitly stated in the options provided. However, the general practice for working with springs or spring-loaded mechanisms would involve safely decompressing or releasing the spring's tension to avoid injury or damage to the spring or surrounding components. For an external bending spring, a methodical and gentle approach should be taken.
For instance, when mechanics try to remove a very tight bolt, they sometimes put a length of pipe over the handle of a wrench. This method increases the leverage, allowing for more torque to be applied with the same amount of force. Applying this principle, safely unwinding or relieving the tension in a bending spring would require the right tools and careful handling to avoid potential hazards, such as the spring snapping back or causing injury.
Therefore, without a specific tool or technique mentioned, it is crucial to understand the physical principles involved and proceed with caution. In the absence of the correct method being listed, it would be best to consult a manual or a professional for the safe removal of the bending spring.
