AufgabenstellungWhen one pulls alon

Aufgabenstellung
When one pulls along a two wheeled suitcase, it can under certain circumstances wobble so strongly from side to side that it can turn over. Investigate this phenomenon. Can one suppress or intensify the effect by varied packing of the luggage?

Deutsche Übersetzung
Beim Ziehen eines Rollkoffers auf zwei Rädern kann dieser unter Umständen so stark schwanken dass er umfällt. Untersuche das Phänomen. Kann man das Umfallen durch Umpacken des Koffer verhindern oder beschleunigen?

Leitfragen
Welche Grössen beschreiben den Koffer (bezüglich Translation und bezüglich Rotation)
Welche Grössen sollen gemessen werden?
Welche physikalischen Grössen ändern sich, wenn der Koffer umgepackt wird?
Braucht es eine Störung des normalen Rollens, wenn der Koffer schwanken soll?
Schwankt der Koffer auch, wenn er von einer Maschine gezogen wird? Ist die Körperbewegung beim Gehen notwendig?
Welchen Einfluss hat die Unterlage (rau, glatt …)
Welchen Einfluss hat die Reibung in den Rollen?
Welchen Einfluss hat die Länge des Handgriffes?
Welchen Einfluss hat die Körpergrösse des Ziehenden?
Projektstart
Normquader mit unterschiedlicher Masse, aber gleichen Aussenmassen verwenden. Z.B. Ziegelsteine und Styroporblöcke
Videoanalyse? Dann Marker anbringen

Task
When one pulls along a two wheeled suitcase, it can under Certain circumstances wobble so strongly from side to side, indeed it can turn over. Investigate this phenomenon. Can one suppress or intensify the effect by varied packing of the luggage? German translation When pulling a rolling suitcase on two wheels can these vary so much that it may fall over. Investigate the phenomenon. Can we prevent or speed up the drop by repacking the suitcase? Key questions which quantities describe the case (in translation and regarding rotation) Which variables are to be measured? What physical quantities change if the case is repacked? Does it disrupts the normal rolling when the case is to fluctuate? Varies the case if he is also drawn by a machine? If the body movement while walking required? How does the Pad (rough, smooth ...) What influence does the friction in the roles? What influence does the length of the handle? How does the body size of the towing? Project Start standard cuboid with different masses, but use the same outer dimensions. For example, bricks and polystyrene blocks video analysis? Then attach markers

task: when one group pulls along a two wheeled suitcase, it can under certain circumstances wobble from side to side so strongly that it can turn over. about this phenomenon. can one suppress or intensify the effect by water packing of the luggage?


the german translation of rollkoffers on two wheels can vary greatly in circumstances that he falls over.investigating the phenomenon. you can drop by repackaging of the suitcase to prevent or accelerate?


what variables describe the suitcase impressed in translation and in rotation) what parameters should be measured?
what physical sizes change, if the case umgepackt? "it takes a disruption of the normal rolling, when the suitcase vary?
, the case also, when he is drawn by a machine? the körperbewegung leaving necessary? "what is the influence of the surface rough, smooth...) what is the influence of the friction in the roll? "what is the influence of the length of the handgriffes? "what is the influence of the height of the test?

normquader project with varying massbut the same aussenmassen use. for example, bricks and styroporblöcke
analysis? then the marker attachment
