After going through the prepared lessons, solve the following problems.
1. Determine the radius of gyration of the shaded area
with respect to the specified y axis.
2. Obtain the moment of inertia of the composite area
about the specified x and y axes.
3. Two 10-in 15.3-lb channels are welded together as shown in
the figure. Compute the value of .
4. Determine the product of inertia of the area shown
with respect to the x and y axes.
5. Determine the moments of inertia and the product
of inertia of the shaded area in the figure with
respect to new centroidal axes obtained by
rotating the x and y axes 30° counterclockwise.
Also, determine the maximum and minimum
moments of inertia of the area.
