Example

 

Carmen photographed an adjustable wrench (spanner). The parts of the adjustable wrench in the second photograph are, from top to bottom, handle with fixed jaw, knurl, pin, and adjustable jaw.

 

This is a photo of a 10-inch adjustable wrench (spanner), also commonly called a crescent wrench.

 

This is a photo of a 10-inch adjustable wrench (spanner) taken apart.

  1. Make a sketch of the wrench, adding labels and dashed lines to give an annotated exploded view.

  2. If the length of the actual wrench is 10 in, what is the approximate scale of the picture?

Solution

  1. This is an image of an annotated exploded view of a 10-inch adjustable wrench.

  2. If the length of the handle and fixed jaw in the exploded view were 5 in—one-half that of the actual wrench—the scale would be 1:2.
