Force of a rubber band
WebThe "-" sign is there because the force is taken to be positive (as is the pressure) but the force of the rubber band is in the opposite direction of the force on a piston, pulling in instead of pushing out. Thus: H=E + PV - FD è q + w + PV - FD If we heat the rubber band with a weight attached, the force F is constant, but the band contracts. WebAug 19, 2009 · Results: Calculate the stretching force (= mg. Note: Since mass is measured in grams, you need to convert it to kilograms (= 10 3 grams) before multiplying by g (= 9.8 m/s 2 )) and the stretch of the spring (= x - x o) for each trial. The stretch of the spring is calculated from two measurements, so you can calculate the uncertainty in the stretch.

WebNov 6, 2002 · Calculate the force applied to the spring/rubber band in each trial (W = mg) Use g = 9.8 m/s 2. Calculate the stretch of the spring/rubber band in each trial (the difference in the starting and ending positions). … Rubber elasticity refers to a property of crosslinked rubber: it can be stretched by up to a factor of 10 from its original length and, when released, returns very nearly to its original length. This can be repeated many times with no apparent degradation to the rubber. Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and technological importance. Elastomers have played a key role in the development of new technol…

Cut a small slot in the middle of the piece of cardboard.
WebExercise 3: Figure 3 shows a stress vs strain plot for a rubber band. As it is stretched (loaded), the curve takes the upper path. Because the rubber band is not ideal, it delivers less force for a given extension when relaxing back (unloaded).
