The whole skill is running the chain in order. Do the recall first, then the drives drill, then the judgment scenario, then walk Riverside's four cartons with the calc closed. The order isn't a suggestion.
Here are the seven steps, scrambled. Number them 1 through 7 in the boxes, from the first move to the last call. Remember where the calculator sits.
Every output on the tab traces back to one package. Write which one, minimum, maximum, or average, drives each output below.
| Output | Which package drives it |
|---|---|
| Roller centers and the smallest gap | |
| Belt width and curve geometry | |
| Speed and throughput | |
| Maximum incline angle |
Read the scenario. Answer without opening a calculator, as judgment rather than data entry.
Three cartons cross your desk: a small case at 8 by 6 by 4 and 2 pounds, a standard case at 14 by 10 by 8 and 8 pounds, and a large case at 20 by 16 by 12 and 22 pounds.
Which drives roller center selection, which drives belt width, which drives the maximum incline angle?
Where would you expect two outputs to conflict badly enough that it forces a design decision instead of a calculation?
Back to Riverside's four cartons. Before you open the Product Spec Calc, answer the three questions below. Then open the calc and check your answers against the outputs. Note anything that surprised you. Your answers tell you whether you're ready to use the calculator or using it to avoid thinking.
| Product | Length | Width | Height | Weight | % Volume | Product Use |
|---|---|---|---|---|---|---|
| Small Case | 8" | 6" | 4" | 3 lbs | 4% | Packaged food |
| Standard Case | 13" | 9" | 3" | 12 lbs | 78% | All clients |
| Tall Case | 10" | 8" | 14" | 18 lbs | 12% | Apparel client |
| Large Case | 22" | 15" | 7" | 28 lbs | 6% | Housewares |
