Leading third
The package…
Recall first, from memory. Then the two scenarios. Then the thirds drill, then your Riverside deliverable. Curves are Session A, inclines and declines are Session B.
Short answers. Pull them from the lesson, not a calculator.
1. A package through a curve occupies more belt than the same package on a straight run. What dimension of the package decides the minimum belt width, and why does the curve become the specification for the system?
2. The static tumble angle covers a stationary package with a centered load. Name the two forces it can't see, and say what each one does at the belt.
3. Direction of travel decides where the risk lands. On an incline, name the dangerous moment and the way the box wants to tip. Do the same for a decline.
4. Gravity roller conveyors are typically pitched how much fall per 10-foot section, and how many rollers have to stay under the product at all times?
Drop a plumb line from the center of mass to the incline surface. Fill in what the package does when the line lands in each third, and note whether you draw the centered load or the shifted one.

Read each one and write your call, then defend it in a sentence or two.
Your layout has a 90-degree curve at a 32.5-inch inside radius, and the largest carton in the mix is 22 by 15. The mix also includes non-rigid padded mailers. The curve output pushes the system wider than the straight sections need, and the cost target wants a narrower run downstream. Decide whether the guardrail taper is acceptable for this specific mix, and defend the decision.
A 15-degree incline passes the static tumble check for the package in question. Name two factors that could still tip a package on that incline despite passing the static calculation, explain what's happening physically for each, and identify the single most dangerous operational moment and the design response that addresses it.
