How do I calculate center of mass using integrals and density?

AI Thread Summary
To calculate the center of mass using integrals and density, the x-bar is determined by the equation \bar{x} = ∫\tilde{x}dm / ∫dm, where \tilde{x} is the product of the x-coordinate and the function value, in this case, x^3. The function x^3 should be included in the integrand for the mass element dm. The density ρ should be factored in front of each integrand, affecting both the x and y calculations. The same method applies for calculating \tilde{y}, maintaining consistency in the approach. Understanding these steps is crucial for accurate center of mass calculations.

Just some things I need to verify:

When finding the x-bar of the function y=x3 using the equation:

\bar{x} = \frac{∫\tilde{x}dm}{∫dm},

Is my \tilde{x} going to be the x distance(which will just be "x") times x3?

Also, will x3 be in the denominator just before "dm"?

The same process is done for the \tilde{y}, am I correct?

If I am also given a density \rho, will that stay in front of each integrand or in front of (\frac{∫\tilde{x}dm}{∫dm})?

Is the same process is done for the \tilde{y} or are there differences?

Thanks!

Thread 'I need a concave mirror with a focal length length of 150 feet?'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
