One-Eared Cat: A Centroid Sample Problem

The video tutorial explains how to solve a centroid problem by identifying shapes, calculating their areas, and determining the center of mass. It covers the additive method for combining shapes, converting centroid coordinates, and completing tables for final calculations. The tutorial provides a step-by-step approach to understanding and solving centroid problems in engineering.

What is the first step in solving a centroid problem using the additive method?

• Calculate the areas of the shapes

• Identify the shapes involved

• Determine the center of mass

• Convert the centroid coordinates

Which method involves adding the areas of multiple shapes to find the centroid?

• Subtractive method

• Multiplicative method

• Additive method

• Divisive method

How do you calculate the area of a triangle?

• Base divided by height

• Base plus height

• Base times height

• 1/2 base times height

What is the area of a square with a base of 5.5 inches and a height of 6 inches?

• 33 square inches

• 30 square inches

• 36 square inches

• 28 square inches

How is the center of mass for a rectangle calculated?

• Base divided by three

• Height divided by three

• Base divided by two

• Height divided by four

What adjustment is needed for the Y coordinate of a triangle's centroid when it is placed on top of a rectangle?

• Subtract the height of the rectangle

• Divide by the height of the rectangle

• Add the height of the rectangle

• Multiply by the height of the rectangle

What is the converted X coordinate for a triangle with a base of 3 inches, originally at X=1?

• 5

• 3

• 2

• 4

What does the Greek letter Sigma represent in the context of centroid calculations?

• Sum

• Difference

• Product

• Quotient

What is the X coordinate of the centroid for the given shapes?

• 3.48

• 2.50

• 2.75

• 3.08

Why should the Y centroid be closer to the top in this example?

• Because the rectangle is larger

• Because the triangle is on top

• Because the rectangle is on the bottom

• Because the triangle is heavier
