A gear with outer radius of r'=5cm move in a clockwise direction causing an interlocking gear with an outer radius of r"=4cm to move in a counter-clockwise direction at an angular speed of w"=25rev/min. What is the angular speed (w') in the outer gear.
QUIZ:
If the sum of the numbers 1 to 100 can
be calculated with Carl Gauss′s method,
then How do we calculate the sum of the
numbers starting from 2 and going up to
100 by twos in an easy way with the same
method?
Or 2+4+6+8+10+...+100=?
