So, the linear velocity of a point of a rotating body located at a distance R 
from the axis of rotation is determined by the formula:

On the basis of the Department “Digital Electronics and Microelectronics 
"of the Faculty " Electronics and Automation” Tashkent State Technical University 
has created new stands of educational laboratory devices and stands for teaching 
phy-sics courses for students of secondary schools and lyceums in all areas of the 
subject of physics

.
From the school physics course in the section "Mechanics", we developed and 
created a training laboratory stand that studies the laws of plane rotational motion 
of a body. The training laboratory stand allows to directly measure all the neces-
sary parameters (frequency, period and angular velocity) of the flat rotation of the 
disk and establish patterns between them with a sufficiently high accuracy.. Это 
осуществляется с помощью полупроводникового датчика. This is done using a 
semiconductor sensor. The measurement results are directly displayed in the 
electronic display located in the instrument panel. A general view of the training 
laboratory stand studying the laws of plane rotational motion is shown in Fig.1. 
The laboratory stand is a training model of an instrument designed to reproduce 
measurements (experiments) on the study of the dependence of the frequency, 
period, and angular velocity of the disk on the plane of rotational motion. 
Fig. 1. Appearance of the training and laboratory stand. 
On the front panel there are: an automatic and mechanical rotating disk, an 
indicator showing the values of the frequency, period and angular velocity of the 
plane rotational movement. output terminals of the regulated power sources and 
the motor, terminals for connection to the inputs of the measuring device, buttons 
for connection to the power supply network, motor speed control controller.
