In the present article an attempt was made to determine some engineering properties of aonla stones and seeds. Stones and seeds were extracted manually from fresh and fully mature aonla fruits. Physical, gravimetric, frictional and mechanical properties of aonla stones, seeds and seed shell were assessed. Moisture content of aonla stone and seed was found to be and % (wb) respectively. Size of aonla stone and seed was recorded and mm respectively. Percent sphericity of aonla stone and seed was found as and respectively. Volume and surface area of aonla stone cm3 and mm2 respectively. Weight of aonla stone was obtained g and thousand seed weight of seeds was . Aspect ratio of aonla stone and seed was and % respectively. Bulk density of aonla stone, seed and seed shell was , and g/cc. Similarly true density was , and g/cc. Porosity of aonla stone, seed and seed shell was , and % respectively. Coefficient of friction of aonla stone, seed and seed shell on mild steel surface was , and respectively. Similarly it was recorded as , and for stainless steel and , and for glass surface respectively. Rupture force of aonla stone was noted as 496 N. | Assessment of engineering properties of Aonla stone and seeds
