How is the speed of a power hacksaw expressed?

Revolutions per minute
Strokes per minute
Feet per minute
Inches per minute

The correct answer is: Strokes per minute

The speed of a power hacksaw is expressed in strokes per minute because this measurement reflects the number of times the blade moves back and forth in a minute. A power hacksaw operates with a reciprocating motion, where the cutting action occurs during the forward stroke. Therefore, understanding the speed in terms of strokes per minute helps in evaluating the efficiency and performance of the cutting operation. The other options represent speeds or movements that are not applicable to the operational characteristics of a power hacksaw. Revolutions per minute typically refer to rotational equipment, feet per minute measures the linear speed of cutting tools or conveyors, and inches per minute is more relevant for continuous cutting operations rather than the discrete strokes of a reciprocating saw. Thus, "strokes per minute" is the most appropriate expression for the speed of a power hacksaw.
