SET OF ELEMENTS FOR STUDYING HARMONIC OSCILLATIONS Description and Specifications for Lab Tenders
SET OF ELEMENTS FOR STUDYING HARMONIC OSCILLATIONS.
SET OF ELEMENTS FOR STUDYING HARMONIC OSCILLATIONS Studying the oscillations of a system consisting of a mass hanging
by a spring enables to train students in the characteristics of
the motion of a harmonic oscillator; consequently they can
become experienced with one of the most powerful models
for the physical interpretation of a wide range of phenomena.
This set of elements can be used to carry out tests on
oscillatory motions in real time by the use of a distance sensor.
The software enables to defi ne and display physical quantities
resulting from measured quantities. Thus it is possible to
analyze the trend of quantities that cannot be measured by a
sensor, that is the energies associated to the development of
phenomena.
TRAINING PROGRAM
• Hooke’s law
• Elastic oscillations
• How the oscillation period of an elastic pendulum depends
on the mass of system
• How the oscillation period of an elastic pendulum depends
on the elastic constant of a spring
• Studying motion from the point of view of energy
• Simple pendulum
• How period depends on length
• Physical pendulum
• Period not depending on oscillating mass
• Relationship between the period of a physical pendulum
and its moment of inertia
• Torsion pendulum
• Relationship between the period of a torsion pendulum and
its moment of inertia
• Relationship between the period of a torsion pendulum and
the geometrical and physical quantities characterizing the
body in torsion.
• Damped oscillations
MATERIAL OF THE EQUIPMENT
1 metallic support with rod; 1 complete support for elastic
pendulum, for simple pendulum and compound pendulum;
1 elastic pendulum; 4 helical springs with different elastic
constants; 2 spheres of different mass; 1 rocker arm with
two cylindrical masses; 1 skein of high-resistance thin wire;
1 compund pendulum with two cylindrical masses; 1 torsion
pendulum with four metallic wires of different length and
section; 1 guidebook to experiments; 1 case
STUDY OF COUPLED PENDULUMS
Two physical pendulums coupled to each other by a slightly
stretched helical spring, can be added to this set of elements;
the spring coupling the pendulums enables to transfer energy
between the two pendulums. Thus the phenomena of resonance
and of beats can be examined.
