Problem 2 (10 points) 2014 Registration at www.ipho.info Contact Secretariat Lulu Hoffmeister Tel.: 04 31 / 8 80-53 87 Fax: 04 31 / 8 80-31 48 E-mail: sekretariat@ipho.info Competition management Dr. Stefan Petersen Tel.: 04 31 / 8 80-51 20 E-mail: petersen@ipho.info IPN • Olshausenstr. 62 • D-24118 Kiel A question of hanging When it comes to hanging toilet paper rolls, opinions differ. Some hang them so that the loose end hangs down in front, but many also do the opposite. The question arises as to which arrangement requires less force to unroll the paper. For this, a simplified model can be considered, in which the toilet paper roll of mass m is, as sketched in the figure, treated as a solid cylinder of radius R that is fixed to the wall by a rod of length L. The roll can rotate freely about its cylinder axis. The maximum coefficient of static friction between the paper and the wall is denoted by $μ$ . Determine the minimum force with which one must pull the paper straight down in each of the two hanging arrangements so that the paper unrolls. State which hanging arrangement is therefore more favourable. Show that situations can occur in which even the strongest toilet paper must tear when one tries to unroll it. State the conditions under which this unfavourable case occurs and briefly explain why this does not happen so often in practice. Problem 4 (15 points) Airbag sensor Acceleration sensors are used to trigger the airbag. A simple sensor consists, as shown in the figure, of three parallel plates of area A, which are connected together to form a capacitor system. The middle plate of mass m can move between the two fixed outer plates. It is braked by two identical, insulated springs of spring constant k. The springs are unstressed when the plate is in the middle. a) State the maximum distance x by which the middle plate is deflected when the moving vehicle is suddenly braked with a constant acceleration a. b) Determine how large the additional capacitance C must be, if the airbag requires a voltage $U_{C} = 0, 15 V$ to trigger and this is to happen at an acceleration of $10 m s^{- 2}$ . Use the values $d = 1, 0 cm$ , $A = 250 cm^{2}$ , $m = 50 g$ , $k = 5, 0 \cdot 1 0^{2} N m^{- 1}$ and $U = 12 V$ . The force that the plates exert on each other due to their charges is not to be taken into account in this problem.

Alcuni appendere in modo che il fine loose appeso giù davanti, ma molti anche fare Il contrario. La questione si pone As to which arrangement richiede meno forza per sfilare la carta. Per questo, un modello semplificato può essere considerato, in cui il roll di massa m è, come disegnato nel Figure, treated as a solid cylinder of radius R che è fissato al muro da un bastone di lunghezza L. Il rollo può ruotare liberamente intorno al suo asse cilindrico. Il coefficiente massimo di frizione statica tra il carta e il muro è denotato da $μ$ . Determina la forza minima con cui uno deve tirare il carta dritto in ogni delle due arrangiamenti di sospensione Così la carta si allontana. Stato quale Il sistema di imposizione è quindi più favorevole. Show that situations can occur in which even Il carta igienica più forte deve strapparsi quando si tenta di sfiorare. Stato Le condizioni in cui questo caso sfavorevole si verifica e brevemente spiegare perché questo non accade così spesso in

Le sorgenti sono Non sono stressati quando il disco è nel mezzo. a) State the maximum distance x by which the middle plate è deflected quando il veicolo in movimento è improvvisamente frenato con una costante accelerazione a. b) Determine quanto grande deve essere la capacità aggiuntiva C, se l’ airbag richiede una voltage $U_{C} = 0, 15 V$ to trigger and this is to happen at an acceleration of $10 m s^{- 2}$ . Usare i valori $d = 1, 0 cm$ , $A = 250 cm^{2}$ , $m = 50 g$ , $k = 5, 0 \cdot 1 0^{2} N m^{- 1}$ e $U = 12 V$ . La forza che le plate esercitano l’una sull’altra a causa dei loro carichi non deve essere presa in considerazione in questo

Problem 3 (15 points) A hot hairstyle The American girls Sofia and Grace exchange travel experiences: “On my trip to Paris last month, my hairdryer burned out,” Grace reports. Sofia thinks that this was probably due to the higher European mains voltage of 230 V compared to the voltage of 120 V usual in the USA, and decides to take precautions for her upcoming trip to Europe. She fits a series resistor between the socket and the hairdryer, so that at home the hairdryer takes up only half of its power. No sooner had she arrived in Europe … State how the story with the hairdryer is likely to continue and justify this physically. Junior problem (10 points) Round 1 When? Registration is open from April 2013. Submission deadlines are in the summer and can be found on the IPhO website. Who? Interested students who, in the 2013/2014 school year, attend a general-education German school and were born after 30.06.1994. Where? The problems are solved as homework. You hand in your work to your subject teacher for correction. How? Four problems from all areas of physics are to be solved. The solutions may be written by hand or on a computer and should be comprehensible but not unnecessarily long. Textbooks may be used provided the sources are cited. Formulas that appear in the standard textbooks do not need to be derived. Only individual work is allowed. Anyone who, in the 2013/14 school year, has not yet reached the second-to-last grade level can earn a bonus of points through the additional junior problem. What can you win? Participants receive a certificate of participation or a diploma. Round 2 When? September to October 2013. Who? The problems are published at the end of August on the IPhO website and sent to all prize winners of the first round. Successful candidates from middle-school physics competitions or Jugend Forscht may also take part. Where?

Problema 3 (15 punti) Un capelli caldi Le ragazze americane Sofia e Grace scambiano esperienze di viaggio: “Il mese scorso, durante il mio viaggio a Parigi, il mio asciugatore di capelli si è bruciato”, riporta Grace. Sofia pensa che questo è stato probabilmente dovuto alla maggiore tensione di corrente europea di 230 V rispetto alla volta di 120 V, come in America, e decide di prendere precauzioni per il suo arrivo viaggio in Europa. She fits a series resistor between il punto di accesso e il secchiatore, così che a casa il secchiatore di capelli prende solo metà della sua potenza. Non prima che arrivasse in Europa … State how the story with the hairdryer is likely to continue e giustificare questo fisicamente. Problema minore (10 punti) Rondo 1 Quando?
