Set of Springs  [105.86 PH]
An assortment of 150 compression and extension springs ranging from 11 to 300 mm in length, 3 to 22 mm in dia and 27 s.w.g. to 13 s.w.g. in wire thickness. In wooden box.
Hook's Law Apparatus  [105.87 PH]
The apparatus consists of a 15 cm adjustable mirror scale mounted on a sturdy support 30 cm 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 50 g slotted weights are recommended for use with the apparatus.
Young's Modulus Apparatus  [105.88 PH]
Searle's pattern. The instrument consisting of two frames connected by a link. The frames are fitted with self cenring chucks. An accurately graduated micrometer screw to read to 01 mm 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 poins 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.
Young's Modulus Apparatus  [105.89 PH]
Simple form but efficient. Consist of a brass scale 10 cms. long and vernier to read 1/10mm with V slides clamps, guides for wire ceiling attachment and tension weight.
Torsion Apparatus (Horizontal)  [105.90 PH]
Searle's pattern, two cast iron feet each with 3 through holes and grub securing screws, separated by 2 supporting rods approximately 700 mm long one of which is graduated in cms and mms, wheel 165 mm dia, over groove moving in ball bearings, mounted on front foot, with spindle carrying split collect chuck for holding one end of test rod 55 cms long 5 mm dia, other end supported with clamping block through rear foot. With two aluminium scales graduated 30-0-30 in single degrees, mounted onpillar 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.
Torsion Apparatus Vertical  [105.91 PH]
It consists of a heavy mild steel frame mounted on a heavy trileg cast iron base. Upper end of the rod 900 mm length and 5 mm dia under test is clamped by a 3-jaw chuck and the lower end is clamped, into the axis of a torsion couple three metal circular scales 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.
