What is the governing ratio for thin walled cylinders?
1 answer:
Answer:
The governing ratio for thin walled cylinders is 10 if you use the radius. So if you divide the cylinder´s radius by its thickness and your result is more than 10, then you can use the thin walled cylinder stress formulas, in other words:
- if
then you have a thin walled cylinder
or using the diameter:
- if
then you have a thin walled cylinder

Complete Question
For each of the following experiments, identify the counting rule that is relevant for determining the number of experimental outcome.Then use the counting rules to determine the number of experimental outcome
First Experiment
A plant manager randomly selects a can of peas from the assembly line and records whether or not the can's label is properly attached , followed by the weight of the can (as less than 14 ounces, exactly 14, or more than 14 ounces).
Which is the correct Counting rule?
1) Multiple-Step Experiments
2) Permutations
3) Combinations
What is the Number of Experimental Outcomes?
Second Experiment
Three branches (A,B, and C) of a bank have open manager positions. Three home-office employees from a pool of five are randomly selected to fill the manager positions. The first home-office employee selected becomes the manager of branch A, the second becomes the manager of branch B, and the third becomes manager of branch C.
Which is the correct Counting rule?
1) Multiple-Step Experiments
2) Permutations
3) Combinations
What is the Number of Experimental Outcomes?
Third Experiment
A stockbroker forms a stock portfolio for a client by randomly selecting three stock from a pool of five.
Which is the correct Counting rule?
1) Multiple-Step Experiments
2) Permutations
3) Combinations
What is the Number of Experimental Outcomes?
Answer:
First Experiment
Counting rule: Multiple-Step Experiments
Number of Experimental Outcomes: 6
Second Experiment
Counting rule: Permutations
Number of Experimental Outcomes: 60
Third Experiment
Counting rule: Combinations
Number of Experimental Outcomes: 10
Explanation:
The explanation of the first experiment is on the first uploaded image
For the second experiment the counting rule is permutation because from the experiment we can see that the order of selection is important
To obtain the Number of Experimental Outcomes:
We have:
For the third experiment the the counting rule is combination because the order of selection is not important
To obtain the Number of Experimental Outcomes:
We have:
