Textbook Question
Chapter 12, Problem 16RQ
- 16. Your supervisor has assigned you the task of designing a set of measuring spoons with a "futuristic" shape. After considerable effort, you have come up with two geometric shapes that you believe are really interesting.
You make prototypes of five spoons for each shape with different depths and measure the volume each will hold. The following table shows the data you collected.
| Depth (d) [cm] | Volume (VA) [mL] Shape A | Volume (VB [ml] Shape B |
| 0.5 | 1 | 1.2 |
| 0.9 | 2.5 | 3.3 |
| 1.3 | 4 | 6.4 |
| 1.4 | 5 | 7.7 |
| 1.7 | 7 | 11 |
Use Excel to plot and determine appropriate power models for this data. Use the resulting models to determine the depths of a set of measuring spoons comprising the following volumes for each of the two designs:
| Volume Needed (V) [tsp or tbsp] |
Depth of Design A (dA) [cm] |
Depth of Design B (dg [cm] |
| ¼ tsp | ||
| ½ tsp | ||
| ¾ tsp | ||
| 1 tsp | ||
| 1 tsp |

An AISI 1018 steel ball with 1.100-in diameter is used as a roller between a flat plate
made from 2024 T3 aluminum and a flat table surface made from ASTM No. 30 gray
cast iron. Determine the maximum amount of weight that can be stacked on the
aluminum plate without exceeding a maximum shear stress of 19.00 kpsi in any of the
three pieces. Assume the figure given below, which is based on a typical Poisson's
ratio of 0.3, is applicable to estimate the depth at which the maximum shear stress
occurs for these materials.
