Which of the following statements regarding self-locking machines is true?
58. Which of the following statements regarding self-locking machines is true?
- Self-locking machines require external mechanisms to prevent motion
- Self-locking machines have threads with high friction coefficients
- Self-locking machines violate the principle of conservation of energy
- Self-locking machines are not used in engineering applications
Answer
The correct answer is: B) Self-locking machines have threads with high friction coefficients
Explanation
Self-locking machines possess threads with high friction coefficients, enabling them to resist external forces and prevent unintended motion.
