I believe there is a mistake at 7:14. I'm getting On=295N, not 174.6N.

I love dynamics. Türkiye is here

On= 294.9

Wasn't the radius between the ball and O when calculating FN supposed to be 0.65 instead of 0.7?

[@PSiEXE]

No because the radius of the sphere is 100 mm, not the diameter. So .1 + .6
