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 51.36 and 8.63 % (wb) respectively. Size of aonla stone and seed was recorded 14.98 and 4.07 mm respectively. Percent sphericity of aonla stone and seed was found as 90.22 and 48.59 respectively. Volume and surface area of aonla stone 17.21 cm3 and 3221.9 mm2 respectively. Weight of aonla stone was obtained 3.31 g and thousand seed weight of seeds was 17.21g. Aspect ratio of aonla stone and seed was 88.80 and 48.59 % respectively. Bulk density of aonla stone, seed and seed shell was 0.310, 0.461 and 0.277 g/cc. Similarly true density was 0.729, 0.666 and 0.752 g/cc. Porosity of aonla stone, seed and seed shell was 57.82, 30.75 and 63.08 % respectively. Coefficient of friction of aonla stone, seed and seed shell on mild steel surface was 0.63, 0.63 and 0.66 respectively. Similarly it was recorded as 0.60, 0.62 and 0.752 for stainless steel and 0.56, 0.53 and 0.63 for glass surface respectively. Rupture force of aonla stone was noted as 496 N.
