EQUIPMENT FOR STUDYING CENTRIFUGAL FORCE.
EQUIPMENT FOR STUDYING CENTRIFUGAL FORCE The equipment for studying centrifugal force consists of a rail
where a low-friction truck can slide. The truck can be loaded
with variable masses. When the rail driven by a geared motor
starts turning, truck is pushed by centrifugal force towards the
external end of the rail. Knowing the speed of rotation of the
equipment, the force developed by the truck sliding along the
rail, and the radius will lead to verify the well-known formula
of centrifugal force. The truck is connected with a pulley
available at one of rail ends, via an inextensible wire; this wire
passes through the pulley and it is connected with a force
sensor. The rotation machine turns with variable speed so that
centrifugal force is determined even versus angular velocity,
besides versus mass and versus the distance from the rotation
centre. The speed of rotation of the rail is detected by a pair
of photogate sensors connected with the datalogger. Thanks
to the datalogger and to its software, the equipment enables
to assess the trend of centrifugal force versus the truck mass,
versus the angular velocity and versus the radius.
The system is equipped with mechanical protection
