Hooke's Law

Code: PHEM0002

A useful apparatus capable of demonstrating the correlation between the elongation produced in a simple spring and the load applied ( i.e., Hooke )

Hooke's Law Apparatus, Ss Scale

Code: PHEM0009

For the demonstration of Hooke's Law that the elongation produced in a spring within elastic limits is proportional to the load applied to it. Also useful for investigating potential energy and investigating masses. Comprises of ametal rod carrying vertically a polished stainless steel scale 0 to 15cm, with provision for its height adjustment. An integrated mass hanger/pointer is connected to the lower end of the spring with the eyeshaped upper end for suspension through an adjustable collar with cross bar, which is positioned above the scale. Complete apparatusmounted on a stable base.

Strain Gauge

Code: PHEM0016

Strain generated on hanging slotted weights on the extreme end of the metallic strip can be observed by using this instrument on interfacing it with instrumentation amplifier. A foil strain gauge is bonded on a spring steel strip mounted on an alluminium panel.

Strip Tester

Code: PHEM0023

To compare the breaking strain, stretch of carry bag handles, strength of newspaper, stretch of plastic film etc. a pair of strong wooden clamps are used. To avoid slipping of strip, clamps have wing nut fixing and a metallic bar attachment system. The clamps can hook on to a standard laboratory clamp with stand and bottom clamp is loaded by means of standard slottedweights.

Wire For Young's Modulus Apparatus

Code: PHEM0030

For use with Young's modulus apparatus, for use as comparison or experimental wire. Available in diameters 18 to 28 SWG (any gauge).

Wire For Young's Modulus Apparatus Another Type

Code: PHEM0037

Brass Wire, For use with Young's modulus apparatus, for use as comparison or experimental wire. Available in diameters 18 to 28 SWG (any gauge).

Wire Holding Metal Chucks

Code: PHEM0044

Wire Holding Chuck, Universal: Plated metal. Has double ended chuck
For holding metal wires securely in the grip. Self centering chuck has two slots orthogonal to each other forming four jaws, which hold the wire at their center and tighten through a threaded sleeve.

Wire Holding Metal Chucks Another Type

Code:PHEM0051

Wire Holding Chuck, Simple: For wires upto 1.2mm diameter.
For holding metal wires securely in the grip. Self centering chuck has two slots orthogonal to each other forming four jaws, which hold the wire at their center and tighten through a threaded sleeve.

Wire Tester

Code: PHEM0058

It is used to test the stretch and bearing strain of tread, wool, hair, wire etc. Provided in pair with an efficient griping system and may be supported from any laboratory stand while slotted weights are applied to the lower end to provide the stretching force.

Young's Modulus Apparatus, Simplified

Code:PHEM0065

Simplified design on the basis of Searle's pattern. Design similar to YOUNG'S MODULUS APPARATUS, but having square rods joined together through a phosphor bronze strip instead of metal frame. One of the rods has 10-0-10 scale with a 0.01mm micrometer head for adjusting the spirit level. Both the rods have self-centering chuck at its top for holding wires and load hooks at the bottom. Also included are ceiling bracket carrying a pair of chucks, a counterpoise weight and a set of twowires, one each of brass and steel.

Young's Modulus Apparatus, Economical

Code:PHEM0072

Useful for studying the relationship between load applied to a wire and the resulting extension i.e., Young's modulus of elasticity of the wire material. 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, are mounted in a rectangular plate, parallel to each other. The plate has a scale 0-40.

Young's Modulus Apparatus, Searle's Type

Code: PHEM0079

Aluminium Frame
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 for noting the reference point. One frame has vertical scale 10-0-10mm with a micrometer head along it 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 included are ceiling bracket carrying a pair of chucks, a counterpoise weight and a set of two wires, one each of brass and steel. The relative displacement between the two frames can be known from the micrometer reading after adjusting the bubble of spirit level.

Young's Modulus Apparatus, Searle's Type Another Model

Code:PHEM0086

Brass Frame
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 for noting the reference point. One frame has vertical scale 10-0-10mm with a micrometer head along it 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 included are ceiling bracket carrying a pair of chucks, a counterpoise weight and a set of two wires, one each of brass and steel. The relative displacement between the two frames can be known from the micrometer reading after adjusting the bubble of spirit level.
