Tolerance Stack Up Analysis

The video tutorial explains a simple Stack Up problem, focusing on dimensions and tolerances. It guides viewers through creating a loop diagram, tabulating dimensions, and calculating the nominal dimension and tolerance for a gap. The tutorial concludes with a preview of more detailed examples and GD&T topics in future lectures.

What are the dimensions and tolerances of the smaller parts in the Stack Up problem?

• 42 plus or minus 0.4

• 28 plus or minus 0.3

• 70 plus or minus 0.2

• 14 plus or minus 0.1

What is the larger dimension in the Stack Up problem?

• 14 plus or minus 0.1

• 70 plus or minus 0.2

• 28 plus or minus 0.3

• 42 plus or minus 0.4

What is the first step in finding the specifications of the gap?

• Determine the sign convention

• Identify the loop diagram

• Label points A and B

• Calculate the sum of dimensions

In the loop diagram, what is the sign convention for moving from left to right?

• Negative

• Positive

• Neutral

• Zero

How is the table of positive and negative dimensions created?

• By listing all dimensions as positive

• By using only the largest dimension

• By listing all dimensions as negative

• By categorizing dimensions based on their direction in the loop

What is the nominal dimension of the gap AB?

• 28

• 14

• 42

• 70

How is the tolerance for the gap AB calculated?

• By dividing the tolerances

• By multiplying the tolerances

• By subtracting the tolerances

• By adding all the tolerances

What is the final specification of the gap AB?

• 42 plus or minus 0.4

• 70 plus or minus 0.2

• 28 plus or minus 0.1

• 14 plus or minus 0.1

What will be covered in future lectures according to the conclusion?

• Advanced calculus

• More detailed examples and GD&T

• Basic arithmetic operations

• Introduction to physics

What is the purpose of the example discussed in the video?

• To explain the concept of force

• To teach algebraic equations

• To introduce basic geometry

• To demonstrate the process of tolerance Stack Up analysis
