Mar 17 2017 · Players with high amounts of axis rotation will favor drier lanes and lower amounts of axis rotation usually like more oil. Higher amounts of friction will cause the ball to lose axis rotation at higher rates. Initial axis rotation ball speed axis tilt and lane friction all dictate when side revolutions become end-over-end revolutions.

Definition. Vr is defined as the speed at which the rotation of the aircraft should be initiated to takeoff attitude.. Rotation speed (V r) cannot be less than V 1.If it is greater than V 1 and it is found that at V r rotation cannot be achieved a subsequent rejected take off may not be possible within the remaining runway length and is likely to result in a Runway Excursion.

Chat Online### Tilt AxisBowler s Reference

Should axis tilt become equal to axis rotation the ball will not hook. In order for the ball to hook axis rotation must always be greater than axis tilt. The axis of rotation defines how far the axis rotates from a pure forward roll in the horizontal direction. The axis tilt defines how far the top of the ball is above the middle of the ball
