Abstract

Comprehensive tests done on physical and mechanical properties of Sterculia urens for the first time, have indicated it to be heavy to very heavy, very strong and very hard, but rather poor in splitting coefficient and retention of shape. On the basis of these tests the timber is considered suitable for use as posts, beams, rafters and tool handles. The timber planes and turns to a smooth finish and is also likely to be suitable after proper seasoning and adoption of alternative jointing techniques (such as use of dowels) for door and window frames, ordinary furniture and joinery.

Abstract

Physical and mechanical properties and suitability indices of Acacia auriculaeformis, an exotic species currently finding favour for firewood farming, have been evaluated. The data suggests that this species would be well worth trying for furniture, joinery, flooring, constructional purposes and tool handles besides turnery articles if logs in suitable girths are available.

Abstract

Rationalisation or the experiments carried out for determining volume/weight ratios for use in transactions of pulpwood at forest site have been proposed. The rationale of working out ratios that would assess the air-dry weight or material based on stack volume measurements has been emphasized, and design of experiments for determining such ratios has been presented.

Abstract

Maesopsis eminii Engl. (musizi) an exotic species, grown in the State of Karnataka was tested for its physical and mechanical properties. The timber is c1a ssified as soft, not tough, moderately heavy and poor in retentign of shape. It is grouped under ordinary group of structural and constructional timbers. It is tentatively recommended for the manufacture of wooden crates, pent-top wooden case, light packing case and light tool handles.

Abstract

The enumeration of sandal is presently being done by the conventional ground survey method which is time consuming and becomes difficult if sandal is located in not easily accessible areas like valley, hills etc. The feasibility of the application of Remote Sensing Technique for sandal enumeration was, therefore, studied. It has been found that aerial photography is feasible for a rapid but at the same time fairly accurate enumeration of the sandal trees in forest areaS.

Abstract

Tensile strength of wood and 3 ply boards of the three species of timbers was evaluated with respect to the inclination Of the fibres. It was found that the plywood is superior to wood at all angles of inclination except when the grains are parallel to the direction of loading.
