Determine the Moment of Inertia Ix and Iy of the composite cross section about the centroidal x and y axes. Parallel Axis Theorem I = I + Ad2
Determine the Moment of Inertia Ix and Iy of the composite cross section about the centroidal x and y axes. Parallel Axis Theorem I = I + Ad2 HINT: 1st find the composite centroidal x and y axes, 2nd find the distance from the centroids of each section to the new composite centroidal axis, 3rd calculate the centroidal Ix and ly and areas using formulas for common shapes, 4th use the parallel axis theorem to calculate the moment of inertia. Also find...

2. The frame shown consists of a very stiff steel beam with a wide-flange beam (W33 X 200), welded rigidly to two vertical channels (C8 X11.5). Assume that the mass of the channels is small compared to the mass of the beam. The area moment of inertia of each channel about its centroidal bending axis is 1.3 in. An eccentric exciter weighting 50 lb is attached to the beam, which weighs 2,000 lb, and is used to excite the frame....
