Question 185General Subjects - QMED

The correct answer is C) 40 to 50 strokes per minute. When using a hand-held hacksaw, the recommended maximum rate of speed for cutting is 40 to 50 strokes per minute. This allows for a controlled and efficient cutting motion, preventing the blade from binding or overheating. Cutting at a higher rate of speed, such as 80 to 100 strokes per minute (option B) or 70 to 80 strokes per minute (option D), can lead to excessive blade wear, reduced control, and potential safety hazards. A slower rate of 10 to 20 strokes per minute (option A) would be too slow and inefficient for most cutting tasks.
