Wood & Metal Cylinder
Catalogue No: 1060280/1
Comprising a cylinder, one half of polished wood and the other half of metal. If paper is wrapped tightly around the cylinder and the rod is held above the flame, the portion in contact with the wood will be quickly scorched while the portion in contact with the metal will remain uncharred, showing the differences in their respective thermal conductivities.

Worcester Circuit Board Kit
Catalogue No: 1091260
For exploring the various concepts of electricity. A moulded plastic base board features terminals, cell holder (D-type) and a grid of metal pillars for connection. Also included are a number of clip-on connection strips and accessories units, enabling a variety of circuits to be constructed quickly. Phosphor bronze connection strips are so designed that when flexed a little, they are easily slipped over the pegs on baseboard, where their natural spring holds them in position and ensures good electrical contact. The kit includes following components:
* Flash Lamp Bulbs – 18 Nos. * Plain Connectors – 12 Nos.

Young’s Modulus Apparatu, Economical
Catalogue No: 1040100
Useful for studying the relationship between load applied to a wire and resulting extension (Young’s modulus of elasticity). Can also be used for comparing elastic moduli of two different wires. Two thick sheet metal strips with clamping screws at the top for wires and metal hooks for the loading masses at the bottom, are mounted in a rectangular plate, parallel to each other. The plate has a scale 0-40 x 1mm along with a movable Vernier of LC 0.1mm, attached to one of the metal strips. Supplied complete with a tension weight and a set of two wires and 1 each of brass 26 SWG and steel 24 SWG.

Young’s Modulus Apparatu, Searle’s Type
Catalogue No: 1040120/1
A specially designed apparatus capable of greater degree of sensitivity and accuracy. Two cast metal rectangular frames hinged together parallel to each other to allow only vertical relative motion, with a spirit level fixed on a cross-bar pivoted across the frames to note the reference point. One frame has vertical scale 10-0-10mm with a micrometer head reading to 0.01mm for adjusting the spirit level. Each frame has a self-centering chuck at its top for holding wires and load hooks at the bottom. Also includes a counterpoise weight and a set of two wires (one each of brass and steel).
