For small theta, theta~=tan(theta) when theta is in radians. So the angle of a "ball" undergoing z_accel and y_accel hung on the end of a string makes with the verticle will be approximately -z_accel/y_accel radians. Converting to degrees, multiply by 180/pi=57.29, or 5.729 times the returned value. Edited by Dave Perry, 2/26/06. Edit by Daniel Dubreuil june 2014: I'd rather say Angle with the verticle (radians) -y_accel/z_accel FG indicated-slip-skid = -(y_accel/z_accel)*10 --> <min-deg>-9.3</min-deg> <max-deg>9.3</max-deg> <!--center> <x-m>0</x-m> <y-m>0</y-m> <z-m>0.10</z-m--> <!-- 0.10 is fitted to the drawing.
