1. Find the moment of inertia about an axis perpendicular to the page and passing through the pin at O. (We'll often just say, about O in the context of this class.) The plate has a thickness of 15 mm, and is made of steel with a density of 7900 kg/m². 150 mm- 1.40 m 1.40 m

Show using analytical methods how the mass moment of inertia changes for a uniform rod by changing the axis about which it rotates. Z Figure 1 - Uniform Rod Q1 dr L

1. A circular disk has a density p(r) which varies as a function of distance from the center of the disk. The disk has a radius R and a thickness t. Assuming p(r) = Po(1-r/R): Calculate the total mass of the disk. a. b. Calculate the moment of inertia of the disk about an axis out of the plane of the page and passing through Point G. C. Calculate the moment of inertia of the disk about an axis out of the plane of the page and passing through Point O. G R
