Abstract

FIELD: physics.SUBSTANCE: device consists of a trolley with a vertically placed rigid screen, with which the impacting body interacts. The device was used to study the influence of the mass ratio of the co-impacting bodies to the exchange of pulses between them under the oblique elastic impact. It is shown, that in the conditions of the experiment conducted in the case if the mass of the impacted body exceeds the mass of the impacting body not less than 50 times, the pulse of the impacted body changes very slightly.EFFECT: improvement of the device.3 cl, 1 dwg

Description

The invention relates to the field of experimental mechanics and is a device (device) for studying the mechanical interactions of physical bodies, namely elastic shock.

A shock close to absolutely elastic can be imagined only by abstracting from those processes that can occur during an elastic shock. In practice, these processes can be of little significance and can be neglected. For example, the impact of a steel ball on a steel plate can, apparently, be considered absolutely elastic or close to that.

Elastic impacts in one form or another are the subject of study in many branches of physics. In classical mechanics, the study of elastic impacts is not given much importance, considering this question quite clear. Obviously insufficient attention is paid to the study of oblique elastic impacts. At the same time, the study of oblique elastic impacts can be of great practical importance. The subject of research can be various aspects of this phenomenon, especially their quantitative side. The present invention can be used both on Earth and in space.

The prototype of the invention can be described in the educational literature, the study of the interactions of spherical bodies (Rowell G. and Robert S. Physics. M., "Education", 1994, S. 122-128).

The invention is illustrated in the drawing (Fig. 1).

Short write-off of the drawing.

In FIG. 1 schematically shows the proposed device (device), consisting of a trolley (1), the mass of which can be changed by placing additional loads (2) on the trolley platform, equipped with a rigid screen (3) in the front part, with which the impacting body can interact (4) , as well as a recording device (5), fixing the movement of the carriage upon impact, while the striking body is accelerated using an autonomously located inclined trough (6) or any other device that provides the desired effect. When operating the device in zero gravity, only the trolley platform can be used, attached to the base of the aircraft with the possibility of longitudinal movement, while additional loads must be rigidly fixed to the platform.

A brief description of the operation of the device.

The striking body accelerates when moving along an inclined groove and elastically strikes at an angle, for example 45 °, against the screen, causing the cart to move.

An example of the use of the invention

A device (device) was used to study the influence of the mass ratio of the colliding bodies on the momentum exchange between them during oblique elastic impacts. It is shown that under the conditions of the experiment, if the mass of the striking body exceeds the mass of the striking body by at least 50 times, the momentum of the striking body changed very slightly.
