The wheel is marked and pointer is fixed to the bracket. The bracket has four holes and can be fixed to the wall also. See Enlarge Click to Enlarge HOOK?S LAW APPARATUS The Apparatus consists of a 15cm adjustable mirror scale mounted on a sturdy support 30cm high, an adjustable hook and a spring with a weight hanger are attached to the top of the rod. A pointer is fastened to the weight hanger, 5 pieces of 20g slotted weights are recommended for use with the apparatus. See Enlarge Click to Enlarge YOUNG?S MODULUS APPARATUS Searle?s pattern. The instrument consisting of two frames connected by a link. The frames are fitted with self centering chucks. An accurately graduated micrometer screw to read to 0.01mm is fitted on one frame. One end of a sensitive spirit level is pivoted to one of the frame, the other end rests on the points of a micrometer screw fitted in the other frame. The bubble of the level is adjusted to its zero mark and the reading of the micrometer observed. The load is then applied and by turning the micrometer screw the bubble is again adjusted to zero. The reading is observed and the difference between the reading gives the extension of the wire. Complete with chucks, ceiling attachment and tension weight. With case. See Enlarge Click to Enlarge YOUNG?S MODULUS APPARATUS Simple form but efficient. Consist of a brass scale 10cms. long and vernier to read 1/10mm with V slides clamps, guides for wire ceiling attachment and tension weight. See Enlarge Click to Enlarge TORSION APPARATUS (HORIZONTAL) Searle?s pattern, two cast iron feet each with 3 through holes and grub securing screws, separated by 2 supporting rods approximately 700mm long one of which is graduated incms and mms, wheel 165mm dia, over groove moving in ball bearings, mounted on front foot, with spindle carrying split collect chuck for holding one end of test rod 55cms long 5mm dia, other end supported with clamping block through rear foot. With two aluminium scales graduated 30-0-30 in single degrees, mounted on pillar supports, which are adjustable along the rod, two pointers with clamp for attaching to specimen, one each of Brass and Steel rods, cord and hook for carrying masses but w/o weights. See Enlarge Click to Enlarge TORSION APPARATUS VERTICAL It consists of a heavy mild steel frame mounted on a heavy tri-leg cast iron base. Upper end of the rod 900mm length and 5mm dia under test is clamped by a 3-jaw chuck and the lower and is clamped, into the axis of a torsion couple three metal circular scale graduated in single degrees which are free to slide on one of the graduated rod can be clamped at any position. Three pointers for clamping to the test rod are provided. Strings to apply the deflecting couple and having pans at their free and pass over bearing pulleys which are clamped to the uprights without weights. See Enlarge Click to Enlarge SCALE PAN Light alloy, 150mm dia with chains and ring. See Enlarge Click to Enlarge BENDING OF BEAM ASSEMBLY For determining young?s modulus for the material of a beam when supported at its extremities. Comprising a metal chrome plated bar 1 metre 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. See Enlarge Click to Enlarge MAXWELL?S VIBRATION NEEDLE All brass N.P. For experiments on rigidity. It consists of a hollow brass tube graduated with scale divided in mms and with vernier to read 0.05mm. 40cms. Long, 18mm dia fitted with a small chuck and carrying a mirror, 2 solid cylinders and 2 hollow cylinders all 10cms long accurately fitted in the bore of the tube and ceiling attachment with chuck. See Enlarge Click to Enlarge WALL BRACKET FOR VIBRATION NEEDLE A heavy metal L shape strip with chuck nuts and two holes for fixing on the wall. See Enlarge Click to Enlarge ELASTIC MATERIALS KIT In this kit various materials such as springs, rubber blocks, wire, rubber cord, tube etc., are provided for class experiments to explore ‘elasticity’ by performing experiments on compression, torsion, extension and elastic limits. The standard pack is one-quarter class kit, i.e. sufficient for eight students and contains: 25 expendable steel springs. 2 wide steel springs 114 x 75mm diameter. 2 soft latex foam blocks. 1 50g reels of 32 s.w.g.
