Technology of Alpine Skiing
ME1520 D Term 2000
Homework 3. Pushing
Due in class on Tuesday, 11 April
Scenario for problems 1-5:
On the flats a 85kg skier is initially going 9m/s in a turn with a radius of 16m.
Neglect air drag. Neglect ski-snow friction.
The skier steps to the inside of the turn with a pure lateral push so that the radius of the turn is reduced to 15m (assume the edge and lean angles change appropriately).
Scenario for problems 6 and 7:
The same skier is still on the flats and once again moving at 9m/s, but now along a straight line. The skier makes a lateral push over a distance of 1m with an average force of 475N. Neglect air drag. Neglect ski-snow friction.
