The irregular area has a moment of inertia about the AA axis of 35 (106) mm4. If the total area is 12.0(103) mm2, determine the moment of inertia if the area about the BB axis. The DD axis passes through the centroid C of the area.
Determine the inertia of the parabolic area about the x axis.
Determine the radius of gyration ky of the parabolic area.
Determine the moment of inertia of the area about the x axis. Then, using the parallel-axis theorem, compute the moment of inertia about the axis that passes through the centroid C of the area. = 120 mm.
Determine the location of the centroid C of the beam's cross-sectional area. Then compute the moment of inertia of the area about the axis.
Determine the moments of inertia Ix and Iy of the shaded area.
The composite cross section for the column consists of two cover plates riveted to two channels. Determine the radius of gyration k with respect to the centroidal axis. Each channel has a cross-sectional area of Ac = 11.8 in.2 and moment of inertia (I )c = 349 in.4.
