My maxiumum g forces are at the apex of the turn. (skis parallel with the fall line)
Consider the following folks; (note, I will attempt to write at a 101 level so all can understand, don't be offended)
The G forces acting on a skier at any moment during a turn are the net effect of the gravity and centrifugal force acting on the skiers Center Of Mass (CM).
In a clean, consistent, carved turn the G forces are lowest at the top of the turn. This is because, here, gravity and centrifugal force work in opposition. Gravity attempts to drive the CM down the hill, and centrifugal force attempts to drive it uphill.
As the turn progresses, and the skis become parallel with the falline, forces increase because gravity is no longer working in opposition to centrifugal force. Here, gravity works perpendicular (90 degrees) to centrifugal force, so it neither intensifies or diminishes G forces. It's because of this that when one is in the falline the amount of G forces generally equates to the amount of centrifugal forces.
As the skier continues along with his carve, leaving the falline, G forces will hit their highest levels. This is because gravity now works on the skier in harmony with the centrifugal forces. Gravity attempts to drive the skier down the slope, as does centrifugal force, and they combine to take G forces to their highest levels,,, higher than during any other phase of the turn.
There are only 2 ways G forces can be maintained or diminished after leaving the falline:
1) Increase the turn radius by reducing the edge angle, which decreases centrifugal forces,,,, or,
2) Release the CM resistance to the G forces and begin the cross over.
There are problems with employing these two options. Option #1 (increasing turn radius) will result in the racer drifting low for the next turn. He/she will be late starting the next turn and will have to struggle to try to get back on line.
Notice in the following montage how the racer maintains her turning radius coming out of the falline (and even reduces the radius) and ends up in a good position (high above the next gate) for the start of the next turn.http://www.ronlemaster.com/images/20...c-gs-2003.html
Option #2 (begin to release the CM when the skis are in the falline and the begin the cross over) is fine if the racer does not need to travel across the hill, if there is little offset to the next gate. But if he/she does need to move laterally across the slope to negotiate the next gate then he/she needs to maintain the edge angle and CM resistance to the forces until the CM's direction of travel has been redirected as needed to move far enough across the slope. Failing to do so puts the racer in too low a line. For the recreational skier this type of early release results in the often observed down the falline skiing with uncompleted turns.
Notice how in the following montage the racer maintains his edge angle and resistance to the G forces well past the time his skis are in the falline (skis are in the falline between image 3 and 4);http://www.ronlemaster.com/images/la...c-2004-gs.html
In free skiing I don't worry about hooking them up early and the max g forces are in the lower 1/3 of the turn rather than the sides of the turn.
In a sense, this is very misguided. First, because of the mis diagnosis of G force intensities through a race turn, which I just discussed above (though he has them right for recreational skiing), , and second because of his mis understanding of the early hook up, which I will discuss now.
Early engagement is typically understood to mean an early carve initiation, before any steering or pivoting takes place, while the skis are still pointing the direction they pointed at the end of the prior turn. This is arc to arc skiing. In contrast to what John says, this type of skiing is more suitable for recreational skiing than racing. Modern racing is seeing ever more pervasive use of a pivot prior to edge engagement. It allows racers to tighten the line beyond what would be allowed with pure arc to arc skiing. This is a harsh and aggressive manner of skiing that is much less called for during recreational skiing. Recreational skiers have the luxury of executing cleaner, smoother, arc to arc turns with edge engagements that are made much earlier in the turn cycle.
Notice in the following montage how the racer executes almost a full 90 degrees of redirection (pivot) of his skis before edge engagement even begins. This pivot move is now very typical on the WC.:http://www.ronlemaster.com/images/20...e-pc-gs-1.html
And finally, referring back to the prior montage, notice that the skis have passed through alignment with the falline before engagement is even initiated. Obviously G forces are greatest after the apex of the turn (the falline). Prior to the falline they were non existent.
