Question 2: We take moments about the y -axis and so we'll need to re-express the expressions x 2 and x 1 as functions of y. If x and y-axes are missing, draw the axes in the most convenient means. This is used to detect comment spam.

For each of the shapes, we need to find the area and the x and y coordinates of the centroid. Get the distance of the centroid of each divided primary figure from the x-axis and y-axis. Where should we place this single mass?

Work by a Variable Force using Integration 8. The rectangles have dimensions 120 x 40, 40 x 50, 120 x 40 for Area 1, Area 2, and Area 3 respectively.

## 5. Centroid of an Area by Integration

We would use this process to solve the tilt slab construction problem mentioned at the beginning of this section. See samples before you commit. The centroid is the term for 2-dimensional shapes. This is used to provide data on traffic to our website, all personally identifyable data is anonymized.

Tilt-slab construction aka tilt-wall or tilt-up. Finding the Center of Mass via the Method of Composite Parts To use the method of composite parts to find the center of mass, we must first break a complex volume down into several simpler volumes.
