The function of brush is to collect current from rotating commutator and supplies the current to external stationary load. The brushes of a DC machine are placed at neutral points because the current in the rotating part drops to zero at the neutral point. If brushes are placed in location other than the neutral points, then the current may be switched off and it causes magnetic field and it may also create voltage spikes and arc at brushes.
To avoid sparking they need to be placed at zero point
Carbon, due to it's high melting point.
That would be Ray Combs, host of Family Feud from 1988 to 1994. After he was fired from Feud, his life started spiraling out of control to the point that he was institutionalized. It was in that institution that he hanged himself.

A reference point helps to explain why we are, where we are.
If you're taking the interstates, it's Mountainburg. If not, it's Combs.
I don't think you can keep the tools and brushes from disappearing when you make it "large". I think that's the whole point of making it "large", which in my opinion is to get rid of some of the sidebars.
The point where your ISP's network connects to your network

The objectives of packaging from the logistics managers point of view is to protect the interest and liabilities of the enterprise or parties involved in the trade. By packaging correctly, managers prevent loses and damages which could increase cost of products as well as inconveniences handling claims.
Electrical contact materials used in switches brushes and relays must possess high thermal conductivity and high melting point.High thermal conductivity dissipates heat effectively and high melting point is to avoid fusing in case of accidental overheating.
