This apparatus is an improvement over the conventional apparatus to show the effects of vibrations in a stretched cord and examine the relationship between frequency, tension and density. A thin steel rod is clamped near one end through two 4 mm socket terminals. This rod passes through the centre of a small solenoid and between the poles of a magnet. Adjustable contact points fitted through a second pair of 4 mm socket terminals make alternating connection with an adjustable contact on the rod. The rod has a small hole at one end for the attachment of thread which passes over a pulley mounted on a bench clamp and supports a scale pan, 75 mm diameter, supplied complete with pulley with clamp and scale pan, 2V A.C. power supply.

Consists of a base board, complete with terminals, a set of metal connection pillars & a number of clips on flexible connection strips & accessory units; enabling a wide variety of electrical circuits to be constructed quickly & easily. The phosphor - bronze strips are so designed that when flexed a little in the fingers, they are easily slipped over the pass where their natural spring holds them firmly in position & ensures a good electrical contact. Supplied with all the necessary accessories.
