Zorluk: KolayWrenches

An apprentice mechanic is organizing four metric combination wrenches on a tool tray. In what sequence should the mechanic arrange these wrenches from the smallest nominal size to the largest nominal size?

  1. 18 mm8\text{ mm} combination wrench
  2. 210 mm10\text{ mm} combination wrench
  3. 313 mm13\text{ mm} combination wrench
  4. 417 mm17\text{ mm} combination wrench

Cevap

The correct sequence from smallest to largest is the 8 mm8\text{ mm} wrench, followed by the 10 mm10\text{ mm} wrench, the 13 mm13\text{ mm} wrench, and finally the 17 mm17\text{ mm} wrench.
Metric wrench sizes directly represent the width across the fastener flats in whole millimeters. Sorting them from smallest to largest follows standard numerical order: 8 mm8\text{ mm}, 10 mm10\text{ mm}, 13 mm13\text{ mm}, and 17 mm17\text{ mm}.

Adım Adım Çözüm

1
Identify the nominal millimeter size stamped on each wrench.
The four values are 13 mm13\text{ mm}, 8 mm8\text{ mm}, 17 mm17\text{ mm}, and 10 mm10\text{ mm}.
Metric hand tools are measured across the parallel flats of the fastener head in millimeters.
2
Sort the millimeter dimensions in ascending numerical order.
8 mm<10 mm<13 mm<17 mm8\text{ mm} < 10\text{ mm} < 13\text{ mm} < 17\text{ mm}
Smaller millimeter numbers indicate narrower jaw openings and smaller fastener applications.
