Young's Modulus Apparatus, Searle's Pattern   (MC-1160)

It comprises two metal frames connected by a link mechanism carrying a spirit level. The wire under test is held in self centering steel chucks capable of holding wires of 1.2 mm diameter (18 SWG). A Micrometer head reading to 0.01 mm is provided for re¬adjusting the sprit level. Supplied complete with ceiling bracket having itself a pair of chucks similar to those on the frame, counter-poise weight, and set of suitable wires, without slotted masses.

Slotted Masses For Above, Iron (MC-1160/1)
18 x 1 Kg masses with 1 Kg hanger, hanger approximately 500 mm high, black painted.

Metal Twisting Apparatus   (MC-1161)

This apparatus is used to compare the degree of brittleness of wires of different materials. Two pin chucks are mounted on stout metal brackets on a base board 240 x 100 mm. Brackets are positioned 100 mm apart. One of the brackets is fixed and other bracket rotatable by handle. The fixed chuck is drilled through to pass the wire under test for pretensioning purposes. The wire is slowly twisted until it breaks and the number of turns required to break samples of different metals noted and compared.

Supplied complete with a set of four wire samples.

Bending of Beam AssemblyBending of Beam Assembly   (MC-1162)

For determining Young's modulus for a beam of metal when supported at its extremities. Comprising a metal chrome plated bar 1 meter long, resting on the knife edges of 2 heavy table clamps, hanger with knife edge support to rest on the beam with micrometer or spherometer attachment and with electric contacts, but without weights.

Maxwell's Vibration Needle   (MC-1163)

For experiment on rigidity. Two solid and two hollow cylinders each 10cm long accurately fitting the bore of a hollow brass tube 40cm long are provided. The tube is also fitted with wire chuck and mirror, graduated scales and verniers on sliding weights. Complete with ceiling attachment.

Hardness of Metal Apparatus   (MC-1164)

This is to determine the hardness of a metal sample by indentation method. A simple apparatus comprising an aluminium tube 750 mm long, 12.5 mm outside diameter. A standard centre punch is provided which is dropped down the tube, the lower end of which rests on a sample under test. The tube ensures that punch is dropped from a constant height and indentation to be measured with a hand microscope of approx. 30x magnification with a built in graticule.

Accessory: Hand Microscope 30x magnification.

Torsion Apparatus   (MC-1165)

Searles horizontal pattern. Two cast iron feet each with three through holes and grub securing screws separated by two rods approx. 700 mm long. one of which is graduated, Wheel 165 mm diameter, over groove, moving in ball bearings, mounted on rear foot, with spindle carrying split collet chuck for holding one end of test rod, other end supported with clamping block through ot foot. With two aluminium scales graduated 30-0-30 degrees mounted on pillar supports, two pointers with clamps attaching to specimen, one each brass and steel rods 5r diameter, cord and hook for carrying masses, but without masses.
