Alamina with constant density rho(x, y) = rho occupies the given region. find the moments of inertia ix and iy and the radii of gyration x double bar and y double bar. the part of the disk x2 + y2 ≤ a2 in the first quadrant

Ix = Iy =

Radius of gyration x = y =  

Step-by-step explanation:

Given: A lamina with constant density ρ(x, y) = ρ occupies the given region x2 + y2 ≤ a2 in the first quadrant.

Mass of disk = ρπR2

Moment of inertia about its perpendicular axis is . Moment of inertia of quarter disk about its perpendicular is .

Now using perpendicular axis theorem, Ix = Iy = = .

For Radius of gyration K, equate MK2 = MR2/16, K= R/4.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
