Problem 2
Consider a rigid body, whose moments of inertia matrix, calculated with respect to the center of mass
and in B-RF coordinates, is:
10
-2
Ig
=
-2
4 -1
11
8 -1
Find the directions of the principal axes of inertia (i.e., find Rgp) and the principal moments of inertia
matrix 19.
Problem -05 Moment of InertiaDetermine by direct integration the moment of inertia of the shaded area(Fig -5) with respect to the y axis.
Use the given values in problem to answer the following:
Find the moment of inertia and radius of gyration of the section of this bar about an axis parallel to x-axis going through the center of gravity of the bar.
The bar is symmetrical about the axis parallel to y-axis and going through the center of gravity of the bar and about the axis parallel to z-axis and going through the center of gravity of the bar.
The dimensions of the section are:
l=51 mm, h=29 mm
The triangle: hT=15 mm, lT=18 mm
and the 2 circles: diameter=7.4 mm, hC=8 mm, dC=7 mm.
A is the origin of the referential axis.
Provide an organized table and explain all your steps to find the moment of inertia and radius of gyration about an axis parallel to x-axis and going through the center of gravity of the bar.
Does the radius of gyration make sense?
In the box below enter the y position of the center of gravity of the bar in mm with one decimal.
