Rubber band extension experiment
Scientific knowledge: before doing the experiment i came to the conclusion that this experiment relates to hooke's law which states that extension is propo. The same elastic band) to ensure that the experiment is as fair as possible the apparatus was set up as shown on the previous page i measured the 'extension' of the elastic band when it was not loaded then i loaded the elastic band with the masses, increasing in 100g intervals each. Hooke's law experiment computer applications assignment 1 an experiment is to be undertaken to determine the behaviour of three materials, in relation to hooke's law two of the materials within their elastic regions and one in it's plastic region. Just about everyone has used rubber bands in the first experiment you will attempt to detect heat flow into or out of a rubber band to do this, you need a rather sensitive heat detector fortunately, you have such a detector with you at all times. Extension of the rubber band experiment to include effects of temperature and wetness however, every rubber band i have used in class has three distinct regions in which the behavior is linear one example of student-obtained data: displacement of rubber band spring constant.
Does the rubber band obey hooke's law experiment and how can i prove this by the use of an experiment the resistance of rubber to extension is also a function of how fast the rubber is extended. The relationship of rubber-band extension to potential energy is quadratic each length of the rubber band is a condition of your experiment conduct 3 trials for each condition for the 3 trials for each condition. The coil spring of a wind-up clock an archer's stretched bow a bent diving board, just before a divers jump the twisted rubber band which powers a toy airplane a bouncy ball, compressed at the moment it bounces off a brick wall an object designed to store elastic potential energy will typically. Rubber band hair dryer experimentavi - duration: 3:10 arun kumar 10,497 views mobile-workoutcom - arms - finger extension with rubber band - duration: 0:23 ethangabby01 1,647 views 0:23 rubber band through thumb - revealed - duration: 2:23. Stretching a rubber band rubber has some strange elastic properties stretch a rubber band and record the extension against load and carefully take the load off again still recording the extension you can plot a graph like that shown in figure 2.
In this prac we are going to do a simple experiment of firstly stretching a rubber band and then unstretching a rubber band we will (50 gram increments would suffice) recording the extension of the rubber band (m) vs the applied force (n. 8 experiment with rubber band 8 experiment with rubber band mon, 12/19/2011 - 17:37 jneujahr overview the class decides on two different numbers of turns to give the rubber band extensions 1 how could a balloon power a car 2. Controlled assesment experiment - the extension of a rubber band depends on the force applied now i will measure the extension of the rubber band without any weight 5 i will now a 2p coins to the bucket. Elastic hysteresis of a rubber band innovative uses elastic hysteresis of a rubber band date professor richard g born, from northern illinois university, devised an experiment to study hysteresis net work done on rubber band during extension and return products mentioned dual-range. The thermodynamic properties of elastomers: introduction we are all familiar with the very useful properties of such objects as rubber bands, solid rubber balls, and tires materials such as these, which are capable of undergoing large reversible extensions and compressions, are called. Lab 1: -- elasticity note: do not begin your experiment until each person in the group has read the background and answered the background questions many things in nature have elastic properties a rubber band is one example a spring is another.
Rubber band extension experiment
Rubber band stretching this practical is very similar to the 'stretching a spring' experiment, however the results will be vastly different the mass/extension ratio of a rubber band is different and the results taken should prove that hooke's law does not apply.
Next week in the laboratory you will determine whether a rubber band obeys hooke's law day one describe in words from your experiences how the force applied by a spring relates to the spring's extension relate your experiment to a future class discussion of hooke's law lab student. 4 in an experiment to measure the extension of a rubber band the following from ma 503 at usc. I am doing a lab experiment and the objective is to find the efficiency of an elastic band distance to ceiling=29m i varied the extension of the rubber band for each time i repeated the experiment. Elasticity - real-life applications follow city-datacom founder on our forum or @lechmazur when a piece of rubber is subjected to tension, as, for instance, if one pulls a rubber band by the ends, the kinks and loops in the elastomers straighten once the stress.
Investigating how weight affects the extension of a rubber band aim: to see if there is a relationship between the weight hung from a rubber band and the. Stretching rubber bands posted mon, 03/04/2013 - 17:19 to describe the stretching action of rubber bands this allows us now to make predictions before we do an experiment for example, a thicker rubber band should have a larger spring constant due to its larger cross-sectional area. Apparatus and materials dynamics trolley runway forcemeter rubber bands light gates and electronic timer (optional extension) balance a trolley started and stopped by catapults class practical c an extension experiment is to calculate the kinetic energy of the trolley. A flashcard question and video tutorial from about investigating how a rubber band stretches as it is loaded with more force che. The stiffness of rubber click here for actual instead the rubber band snaps with very little extension look back over the balloon experiment, where the deformation of rubber under biaxial tension was demonstrated.
