INSTALLATION FOR STUDY OF EFFECT OF IMPACT LOAD AT BAND OF BEAM

摘要

Installation for study of effect of impact load at bend of beam that has basis with controlled screw-stems, sample-beam with rectangular cross section that rests on hinged to basis fixed and hinged movable supports, rod that is fixed on basis in middle between the supports and normally to basis, load-ball that is held in initial state with electric magnet that is fixed on holder, with displacement of which by rod given height of fall of load-ball is set, special catcher that is fixed on beam that provides wedging of the load-ball at impact and its following motion together with beam as one part. At the middle of the beam under the beam laser or luminodiode pointer is fixed, its ray is directed normally to plane of vibration of the beam to discrete light-sensitive ruler that is fixed on the rod in vertical position and connected through quick interface to personal computer.
