Springs in this lab, you will do the following: determine the spring constant for a spring by stretching it determine the spring constant for a spring by oscillating a known mass model the motion of the spring with numerical methods and compare periods of oscillation spring constant the spring constant is a measure of the. I always recommend that students make a graph of some type of linear function and find the slope of that line in this maybe i can say that by using the slope to calculate the spring constant, it is less work ok, so i am going back to recommending the graphing method without even doing the experiment. Meaning of the spring constant for when hooke's law (f = kx) is introduced in class a student's personal extension of the rubber band experiment to include effects of temperature and wetness a basic introduction to before starting: apply the largest force you're likely to use, and find out how far the spring stretches. Using the known spring constant and equation 5, calculate what the period t of oscillation should be for each of the masses report them in table 1 compare them to the t that was representative results of the experiment, conducted with a spring of constant k = 10 n/m, are shown in table 1 the plot of f versus the.
Vol-11, no-2, june-2011 experiment-339 f measurement of spring constant by static and dynamic methods sarmistha sahu dept of physics, maharani lakshmi ammanni college for women, bengaluru- 560012 india are applied for determining the spring constant in the dynamic case static mode. Where the spring constant, , is a measure of the stiffness of the spring your task is to design an experiment to determine the relationship between the applied force and spring extension, and if the relationship is linear as suggested by hooke's law, determine a value for the spring constant additional instructions are. Tion with a viscous damping model to determine a value for k  this procedure can be used with cantilevers of any shape, but relies on experimental determination of viscous damping behavior the ther- mal method uses the equipartition theorem to deter- mine cantilever spring constants  if the power spectrum of the. General science laboratory 1110l lab experiment 5 the spring constant objective: to determine the spring constant of a spiral spring apparatus: pendulum clamp, aluminum pole, large clamp, assorted masses, mass hanger, spiral spring, ruler, and 2-meter stick theory: a spring constant is the measure.
By steven holzner any physicist knows that if an object applies a force to a spring, then the spring applies an equal and opposite force to the object hooke's law gives the force a spring exerts on an object attached to it with the following equation: f = –kx the minus sign shows that this force is in the opposite direction of the. By varying the added mass and measuring the resulting frequency of the probe's internal free oscillations, the effective mass and spring constant of the probe's moveable parts can be found weighing of the probe parts and conducting a hooke's law experiment provide static verification of these parameters study of the.
Pva #16: in this activity, you will verify hooke's law for a spring and determine its spring constant, k. Experiment summary: students will invesfigate hooke's law and determine the spring constant for two springs and a rubber band students will stretch two different springs and a rubber band, while measuring both the distance elongated and the force required to extend the springs from this data, students will calculate the. This experiment provides students with the possibility of understanding the differences between theoretical models that include well-known corrections to determine the frequency of oscillations of a spring-mass system keywords: spring-mass system, hooke's law, elastic constant, simple harmonic motion,.
Find a spring constant using hooke's law hooke's law states that the restoring force of a spring is directly proportional to a small displacement in equation form, we write f = -kx where x is the size of the table are plotted on the graph below note that the points fall precisely on the line since this is a virtual experiment. Springs objectives in this lab we will study properties of springs we will see if the springs obey hooke's law and measure the force constants of a few springs we will also study some you will use hooke's law (equation 1) to determine the spring constant, k, of the spring in the experiment as the name implies,. Tap 227- 6: hooke's law more than one spring aim to find out how the spring constant for systems of springs is related to that of a single spring requirements steel springs, tensile with weaker students it will be necessary to carry out the experiment for them to 'see' how spring systems combine k more able students. Stretch (or compression) graph the slope of this graph is known as the spring constant, while the vertical intercept is the initial loading force various springs of different construction are included, so students can better understand the physical meaning of the spring constant the spring is then compressed (or stretched).
High school science science projects: hooke's law: calculating spring constants forces cause objects to move or deform in some way newton's third law states that for every force, there is an equal and opposite force this is true for springs, which store and use mechanical energy to do work springs are elastic, which. Learn about elasticity and how to determine the force exerted by a spring springs are an essential part of almost all moderately complex mechanical devices from ball-point pens to racing car engines there is nothing young's modulus can be defined at any strain, but where hooke's law is obeyed it is a constant.
Despite the fact that numerous methods described in the literature can be applied to determine the static flexural spring constant of micro- and nanocantilever sensors, experimental techniques that do not require contact between the sensor and a surface at some point during the calibration process are still the exception. Demonstrate how to find spring constants of springs find the relationships (if any ) between amplitude, mass, and period of oscillation in a simple harmonic motion with the materials provided, design an experimental setup in which you make a cart oscillate between two end points on a horizontal track note: a. The goal of the first part of the experiment is to determine how much an extension spring extends per newton of applied force you will measure the amount the spring extends as the applied force is changed the data will allow you to determine the spring constant, which measures the strength of the spring 1 set up the. The spring constant k is different for different objects and materials it is found by carrying out an experiment for example, the unloaded length of a spring is measured different numbers of slotted masses are added to the spring and its new length measured each time the extension is the new length minus the unloaded.
