For the beam cross section described in Prob. 12.3-5, calculate the centroidal moments of inertia Ixc and Iyc with respect to axes through the centroid C such that the xc axis is parallel to the x axis and the yc axis coincides with the y axis.
Prob. 12.3-5
The cross section of a beam constructed of a W 24 × 162 wide-flange section with an 8 in. × 3/4 in. cover plate welded to the top flange is shown in the figure. Determine the distance from the base of the beam to the centroid C of the cross-sectional area.

Create a personal checklist (below) to demonstratemethods of simplification of series-parallel circuits. Your checklist should contain the following:
Diffusion of carbon into BCC iron for 12 hours at a temperature of 5000C results in a carbon concentration of 0.2 wt% at a depth 2 mm from the surface. At what depth would the concentration be 0.2 wt%, if the diffusion occurred for 6 hours at 8000C?
For each case, determine the specific volume at the indicated state. Locate the state on a sketch of the T-v diagram.
