Abstract

Through the present study, the TENSILE FORCE required, to separate the grain from paddy was measured. The velocities related to separation of grain from paddy were chosen 100, 200, 300, 400, and 500 mm/min, and the force required for failure of stem at 100, 300, and 500 mm/min velocities were determined through application of an Intron device. The data were analyzed through a completely randomized design. The results showed that velocity significantly affected the required force to separate the grain from paddy as well as failure of stem. With an increase in tensile velocity from 100 to 500 mm/min, the required force to separate the grain from paddy decreased from 4.77 to 1.09 N and the required force for failure of the stem decreased from 33.43 to 8.41N. Also, the normal stress acting upon the stem as a due requirement force to separate the grain was calculated. The ultimate stress (rupture stress) of stem (the required force for the stem yield) was calculated. Finally the SAFETY FACTOR for the TENSILE FORCE applied to the stem to separate the seed from the stem at velocities of 100, 300 and 500 mm/min, were respectively calculated as 5.74, 6.03 and 6.45.
