Extracts from this document introduction be 1310 density laboratory report the purpose of this lab experiment is to determine the density of four objects of various engineering materials and to perform an accurate error analysis of the measurements taken these errors include uncertainties due to random variations and.
In a bifilar suspension, the pendulum body is suspended over two threads the pendulum body oscillates in a plane purely translationally without rotation this kind of pendulum can be considered as a mathematical pendulum in a trifilar suspension with three threads, the pendulum body is set in a torsional vibration.

Page 1 m41 lab m4: the torsional pendulum and moment of inertia introduction a torsional pendulum, or torsional oscillator, consists of a disk-like mass suspended from a thin rod or wire when the mass is twisted about the axis of the wire, the wire exerts a torque on the mass, tending to rotate it back to its original. This set of machine kinematics multiple choice questions & answers (mcqs) focuses on “bifilar and trifilar suspension” 1 in shm, acceleration is if the radius of gyration of a compound pendulum about an axis through cg is more, then its frequency of oscillation will be a) less b) more c) same.

You will set-up an equation for the period of oscillation of a complex pendulum as shown in figure 1 dimensional analysis will be used to ensure that the equation is dimensionally correct and you will subsequently determine experimentally the exponents in the proposed equation this is an idealised experiment, where. The common methods available for the determination of moment of inertia are the following: torsional (trifilar) pendulum (see fig 1, on page 2) compound pendulum (see fig 2, on page 3) calculation (see fig 3 on page 4) goals 1 to determine the moment of inertia of an object by use of the trifilar pendulum method 2.
Page 1 the model was constructed with the square of the period of oscillations in the small angle approximation being proportional to the length of the pendulum the model was supported by the data using a linear fit with chi- squared respect to the lab atomic clock the final result of g takes into account the correction. 6 to perform the experiment of balancing of rotating parts and find the unbalanced couple and forces 7 to study dynamically equivalent system 8 determine the moment of inertial of connecting rod by compound pendulum method and trifilar suspension pendulum 9 to study the various types of dynamometers 10.
