Young's modulus = stress/strain = (fl 0)/a(l n − l 0) this is a specific form of hooke's law of elasticity the units of young's modulus in the english system are pounds per square inch (psi), and in the metric system newtons per square metre (n/m 2 . experiment 14: hooke's law and simple harmonic motion purpose (1) to study hooke's law for an elastic spring (2) to study simple harmonic motion of a mass suspended from an elastic spring apparatus helical steel spring with supporting stand and scale, set of slotted weights with hanger, timer, laboratory balance. Based on this, a concept lattice, formal concepts, subconcept-superconcept relations, partially ordered sets, supremum and infimum of the lattice and implications between attributes (duquenne-guigues base), were determined for the ecosystem-culture relations. Mathematically, the period of oscillation of a simple harmonic oscillator described by hooke's law is: this equation tells us that as the mass of the block, m , increases and the spring constant, k , decreases, the period increases.
And this law is called hooke's law, and it's named after-- i'll read it-- a physicist in the 17th century, a british physicist and he figured out that the amount of force necessary to keep a spring compressed is proportional to how much you've compressed it. In the classroom i think i'd give it some separation from the first part of the activity- though i do think you could flow fairly smoothly from the first investigation (hooke's law) to the second (simple harmonic motion. Here, we generalize the idea to elastic potential energy for a deformation of any system that can be described by hooke's law hence, where is the elastic potential energy stored in any deformed system that obeys hooke's law and has a displacement from equilibrium and a force constant.
Development of new concept and design of high temperature tube recuperator purpose of development was to elaborate the new concept, designs and mathematical models of hightemperature tube recuperators of prolonged 2 - 5 times service life in conditions of attack of corrosive media. In this case, there is a theoretical prediction (that we will make use of later) called hooke's law, that says that the stretch of a spring is proportional to the applied force (in symbols, f = kx, where k is a constant. Simple harmonic motion (shm) occurs whenever the restoring force if proportional to the displacement from equilibrium simple harmonic motion can be used to approximate small vibrations. Natural oscillation '' '''' circular motion uniform circular motion the motion of an object in a circle at constant speed the system is made to oscillate at the frequency of the dri ving force resonance driving force at ef)d of each s. Simple harmonic motion and its geometric representation derivation of its equation concepts of amplitude, oscillation, time period, frequency and phase with their mathematical expressions.
The requirements for simple harmonic motion, (3) to learn hooke's law, (4) to verify hooke's law for a simple spring, (5) to measure the force constant of a spiral spring, (6) to learn the definitions of period and frequency and the relationships between them, (7) to. You are working on a set of simple harmonic motion problems you have already worked through the sound problem set thursday monday:a quiz on concepts of shm and sound, followed by problem solving. Mechanics: mechanics, science concerned with the motion of bodies under the action of forces, including the special case in which a body remains at rest of first concern in the problem of motion are the forces that bodies exert on one another.
Physics lab report guidelines summary the following is an outline of the requirements for a physics lab report a experimental description 1 provide a statement of the physical theory or principle observed during the exper. Hooke's law, damping, elastic potential energy, friction, harmonic oscillation, simple harmonic motion, spring constant, spring energy, springs, springs record cloner: metadata instance created september 25, 2012 by caroline hall. Elasticity elasticity is the property of an object or material which causes it to be restored to its original shape after distortion it is said to be more elastic if it restores itself more precisely to its original configuration.
- object: the objective of this lab is to obtain the spring constant by using the simple harmonic motion of the spring-mass system once the spring constant is obtained it is to be compared to the spring constant obtained by hooke's law.
