Consider a planar lamina whose density function is given by delta(x,y), measured in kg/m^2. Assume x and y are measured in meters.
What are the units of the first moment of the region about the x-axis?
What are the units of the second moment of the region about the x-axis?
Homework Answers
First moment of inertia depends on mass and it's distance r from axis of rotation.while second moment of inertia depends on mass and square of its distance from axis of rotation.
So unit of first moment of inertia is kg-m
Unit of second moment of inertia is kg-m2
Hope this will help!

lamina with density ρ(x,y) = 3 √{x2+y2} occupies region D, enclosed by the curve r = 1−sin(θ). Which of the following statements is the best description of the center of mass of the lamina? Find the moments of intertia about the x-axis, the y-axis, and the origin for the lamina. Yes, the integrals can be done by hand, but why put yourself through that? You may round your answers to the nearest 0.01.
