The law of conservation of angular momentum is one of the major concept in classical physics, :) and the universe is assumed to born from the Big Bang.:rolleyes: As the angular momentum of a point is meaningless, why do all the galaxies rotate?:mad: where does the initial angular momentum comes...

My Maytag dryer does not work today. When I open the door, the light is not so the electricity is on. But, the drum dose not rotate. Could anybody help? Thanks.

Kenmore Model 110.87872100, drum will rotate when it is empty, when clothes are in it it will not. Drum can be turned by hand. I am assuming that I need to replace the belt and tensioner. How do I get the top off to get this done? Pyromsatc

Hello! I'm trying to figure out how to calculate the resultant polar coordinates of a triangle following the triangle's 45 degree rotation about it's own center of mass. I've seen how to rotate the triangle using: In 2D, you make (X,Y) from (x,y) with a rotation by angle t so: X =...
