4.) Moment of Inertia About the x-axis Ix 5.) Moment of Inertia About the y – axis Iy 6.) Polar Moment of Inertia about the axes Jo 7.) Moment of Inertia About the centroidal x-axis Ix note: In locating the centroid of the entire section, Varignon's Theorem. Varignon's Theorem locates the centroid of a composite body. I hope you will use the formulas I will be giving.
First of all, I already ask the first Tutor in Bartleby to solve the 3 questions which are the 1.) Total Area AT 2.) Centroid about the x-axis ȳ (y-bar) 3.) Centroid about the y – axis x̄ (x-bar).
This is his computations:
A1= 3400, A2=800, A3=706.85834, A4=176.71458
Y1=42.5, Y2=26.666, Y3=52.7324, Y4= 62.5
X1=20, X2=53.333, X3=52.7324, X4=17.5
Total Area: 4730.14376
ȳ=40.604
x̄ (x-bar) = 30.6224
Please, I want you to solve the:
4.) Moment of Inertia About the x-axis Ix
5.) Moment of Inertia About the y – axis Iy
6.) Polar Moment of Inertia about the axes Jo
7.) Moment of Inertia About the centroidal x-axis Ix
note: In locating the centroid of the entire section, Varignon's Theorem. Varignon's Theorem locates the centroid of a composite body. I hope you will use the formulas I will be giving.
