摘要
FIELD: physics, devices for education. SUBSTANCE: device has two pendulums which are designed as platform which has tape feeding mechanism and which vibrates by hanging on double-wound suspender. In addition device has writing unit which is designed, for example, as funnel with sand or liquid and is hanged on double-wound suspender. Immovable ends of double-wound suspenders are connected to horizontal stands, one of which is mounted rigidly, another one is hinged for fixation either along with or at right angle with respect to first one. Clippers of pendulums length are located on vertical struts for variation in pendulums oscillation frequency. EFFECT: demonstration of addition of parallel or perpendicular harmonic oscillations. 2 cl, 1 dwg
