2. Given Figure 2 below, complete the following tasks: a). Determine the position of the centroid using point P as a reference b). Determine the position of the centroid using point Q (centroid of area 2) as a reference c). Determine the position of the centroid using the Link Polygon Method d). Compare and comment on all three methods e). Determine Ixx using the Parallel Axis Theorem f). Determine lyy using the Parallel Axis Theorem g). Determine the radius of gyration about the X-axis (rx) and Y-axis (ry) h). Which axis is strongest in bending and why? Use the second moment of inertia and the radius of gyration to help explain your answer. 60 40 10 40 30 20 60 4 PL 130 Figure 2 2.
