MoreTrajectory models (for shell lifters of various heights and face angles) generally track the fate of the lifter ball, the ball that sits against the lifter and plate (Royston, 2001). At constant mill speed, ball trajectories should degrade (i.e., balls fall more towards the bulk of the charge than the toe)
MoreA video processing system uses at two cameras to determine the 3D position of a ball in a series of frames. The future trajectory of the ball is calculated. The system uses at least four cameras so as to allow some redundancy in the system. The established trajectory is used to establish the likely occurrence of an event, principally for lbw determination in cricket.
MoreIn the table below I used the term mid-range trajectory, abbreviated MRT. A maximum bullet rise of 1.5 inches is appropriate for shooting small animals, as they present a small target, particularly if head shots are necessary. Allowing a greater mid-range trajectory might result in shooting over an animal at an intermediate distance.
MoreHere we are discussing the trajectory of, say, a cannonball which is shot from some angle into the sky, as it traverses both horizontal distance ( x), and at the same time goes up and then down in the vertical direction ( y) as shown in this figure. So the image of the cannonball may be traced as a curve in the x y plane, with y playing the ...
