Integrating a Vector Field Over a Circular Disk

Click For Summary
SUMMARY

The discussion focuses on integrating a vector field over a circular disk, specifically the integral expression \int_{ \vec{r}\in{A}} \frac{ \vec{v}+ \vec{\omega}\times\vec{r}}{| \vec{v}+ \vec{\omega}\times\vec{r}|}d^{2}r, where A represents the area of the disk with radius R. The variables \vec{v} and \vec{\omega} are defined as the translational and angular velocities, respectively, and are constants throughout the integration. The integral is evaluated over the area of the disk, with \vec{r} vectors originating from the center.

PREREQUISITES
  • Understanding of vector calculus

Hi,
How do integrate this? I wish to see it step by step and I'm glad for any help i can get.
\int_{ \vec{r}\in{A}} \frac{ \vec{v}+ \vec{\omega}\times\vec{r}}{| \vec{v}+ \vec{\omega}\times\vec{r}|}d^{2}r
where A is area of disk with radius R.

Can you explain some details? Where does the integral come from? Are v and omega constant for all r? Is omega perpendicular to the disk?
 
\omega is the angular velocity of the disk, v is the translational velocity. v and \omega are constants. Integration extends over the area of the disk with \vec{r} vectors starting at the center.
