Beam Deflection and Moment of Inertia

This video tutorial guides students through the process of using Excel to calculate and graph beam deflection versus moment of inertia. It covers data entry, orientation and measurement of beams, calculation of cross-sectional area and moment of inertia, and the creation of a graph. The tutorial emphasizes the importance of correct data entry and formula application, and concludes with instructions on saving and submitting the completed work.

What is the primary goal of the beam deflection activity?

• To create a deflection versus moment of inertia graph

• To calculate the weight of the beam

• To measure the length of the beam

• To determine the color of the beam

What information should be entered at the top of the Excel sheet?

• Beam weight

• Beam material type

• Personal information and block number

• Beam color

How is the cross-sectional area of a beam calculated in Excel?

• By adding the base and height

• By multiplying the base and height

• By dividing the base by the height

• By subtracting the base from the height

What is the formula for calculating the moment of inertia in this activity?

• I = B + H^3 / 12

• I = B * H^3 / 12

• I = B - H^3 / 12

• I = B / H^3 * 12

What is the deflection equation used in the activity?

• Delta = FL^2 / 48EI

• Delta = FL^3 / 48EI

• Delta = FL^3 / 24EI

• Delta = FL^2 / 24EI

What is the weight of the person used in the deflection calculation?

• 450 pounds

• 150 pounds

• 250 pounds

• 350 pounds

What type of chart is recommended for visualizing deflection versus moment of inertia?

• Scatter plot

• Bar chart

• Line chart

• Pie chart

Where should the graph be placed in the Excel sheet?

• At the top of the sheet

• In the middle of the sheet

• Right under the data

• In a separate sheet

What should be done to ensure the graph and data fit on one page?

• Increase the font size

• Change the graph type

• Use page break preview

• Add more data

What is the relationship between moment of inertia and deflection as observed in the graph?

• Deflection remains constant

• Deflection decreases with moment of inertia

• Deflection is unrelated to moment of inertia

• Deflection increases with moment of inertia
