Carleton University Laboratory Report Course #: Phys1003 Experiment #: 3 Spring Constant Experiment Date Performed: October 29, 2017 Date Submitted: November 06, 2017 Lab Period: Partner: Station #: 3 TA: Dylan Purpose: The purpose of this experiment was to determine the spring constant for a given spring. This was done by two different methods; by measuring extension as a function of the applied load, and by

measuring the frequency of the oscillation of a mass suspended by the spring. These methods are called the static and the dynamic method, respectively. Theory: Static method: All solid substances have a property known as elasticity. This property allows objects to regain their original shape after being deformed by an applied force. However, there is a certain point where a deformed object with elastic properties will not regain its original shape, known as the elastic limit. Hooke’s law can be used to express the force applied on a spring, as a function of the extension (displacement from equilibrium). This law only works if the object is not deformed beyond its elastic limit. It is expressed as: F = kx Dynamic method: The angular frequency, ?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
