Rotating apparatus for determining angular acceleration as a
function of the torque and for determining the moment of inertia
depending on mass and distance from an axis.
An axle on agate bearings supports a cross bar to which weights
can be attached. The force from a driving weight is conveyed to
the axle via a string wrapped around the axle and passed over a
pulley and a second multiple pulley on the axle itself.
UME-05 ARCHIMEDES PRINCIPLE
calculated according to Archimedes' principle
when the weight of the displaced fluid is
determined. The "Archimedes' cylinder" clearly
demonstrates this principle.
UME-08 FALLING SPHERE VISCOMETER
Höppler-type falling sphere viscometer for simple but
accurate The sphere rolls and slides inside an inclined
cylindrical tube filled with the fluid to be tested. The viscosity
is measured in mPa s and is derived directly from the time
the sphere takes to fall a specified distance through the fluid
in the measuring tube. The tube can then be turned
upside-down so that time the sphere takes to fall back can
also be measured. The tube is situated inside a water bath,
which can be filled with water at a specific temperature in
order to measure how viscosity depends on temperature.
UME-03 NEWTON's SECOND LAW
Law, and the relationship between The distance-time law,
the velocity time law, and the relationship between mass,
acceleration and force are determined with the aid of the
demonstration track rail for uniformly accelerated motion
in a straight line.
UME-02 Hooke's law
In this experiment the deformation which is caused
by the weight of "mass pieces" on two
helical springs is measured. The deformation is a
characteristic feature of each spring,
nevertheless one can observe that a fundamental
law is ruling here. It is the goal of this
experiment to verify this law - Hooke's Law.
UME-01 Measuring of the basic constants
UME-09 SHM PENDULUM
A mass, considered as of point form, suspended on a thread
and subjected to the force of gravity, is deflected from
oscillation thus produced is measured as a function of the
thread length and the angle of deflection.
UME-12PENDULUM USING SPRING
Determine the oscillation period T of a spring
pendulum for various masses m on two springs with
different spring constants D.
UME-07 FREE FALL
Apparatus for measuring the time it takes for a
ball to fall a certain distance using a digital
timer. Very easy to set up and use but
nevertheless highly A micro-magnet holds the
ball in its start position. Three contact pins
under the release mechanism ensure that the
start position of the ball can be reproduced and
act as the contacts of a switch that opens when
the ball is released, thus triggering the
beginning of the timing measurement. When the
ball strikes the contact plate at the bottom, the
timer is stopped. The ball is also held firmly on
the plate so that it does not bounce. The height
through which the ball drops can be adjusted to
a fraction of a millimetre and read off a scale on
UME-10 STATIC AND DYNAMIC TORSION
To investigat torsion as applied to bars with cylindrical
geometry and to determine both directivity values and shear
UME-13 SURFACE TENSION OF LIQUID
A blade is immersed horizontally in the liquid and is
slowly pulled out upwards while measuring the
pulling force. The lamella of liquid that forms at the
blade “breaks away” when the force exceeds a
certain value. From this force and the length of the
blade one can calculate the surface
UME-14 Mechanical waves
Some examples of where mechanical waves arise include a stretched coil
spring, where the waves are longitudinal, or a taut rope where the waves
are transverse. In either case, standing waves will be set up if one end of
the carrier medium is fixed. This is because the incoming wave and the
wave reflected at the fixed end have the same amplitude and are
superimposed on one another. If the other end is also fixed, the only way
that waves can propagate is if resonance conditions are met. In this
experiment the coil spring and the rope are fixed at one end. The other
end, a distance L from the fixed point, is fixed to a vibration generator,
which uses a function generator to drive of variable frequency f. This end
can also be regarded as a fixed point to a good approximation.
The intrinsic frequency of the vibration will be measured as a function of the
number of nodes in the standing wave. The speed of propagation of the
wave can then be calculated from this data.
To measure the coefficient of friction for use
of an inclined plane.
UME-11 STATIC AND DYNAMIC TORSION
To investigat torsion as applied to bars with
cylindrical geometry and to determine both
directivity values and shear modulus.
