Effect of moisture content on some mechanical properties of mucuna bean CIGR Journal
Etim, Promise Joseph; Alonge, Akindele Folarin; Akpan, Godwin Edem.
Some mechanical properties of mucuna bean seed were studied at different moisture levels to provide relevant data for development of cracking machine for the seed. The frictional coefficient of the seed on five structural surfaces (plywood, aluminum, glass, steel, and wood) was determined using the incline plane method. The mechanical properties were determined using a Universal Testing Machine. The coefficients of friction of the seed on the respective structural surfaces were observed to have increased with increasing moisture levels. The force to crack the seed on its major axis decreased from 1595.1 to 244.9N as moisture level increased from 4.79 to 18.53% (dry basis), with a similar trend also observed on the minor axis. The deformation on both axes...

Gravimetrical and frictional properties of broilers diets CIGR Journal
Mohhamadi, Vahid; Abbaspour, Behnam; Sharifi, Seyed Davoud; Mirzabe, Amir Hossein.
Abstract: Information on physical properties of broiler chickens diets is not available in literatures and such information is important for design and construction of poultry equipments.  Some physical properties of starter, grower and finisher diet of broiler chickens, namely: gravimetrical (bulk density, true density and porosity) and frictional properties (coefficient of friction filling angle of repose, empting angle of repose and pouring angle of repose) were studied.  Effect of height of falling diets to the containers at 150, 250 and 350 mm and volume of the containers at 500, 600, 1,100 and 2,000 mL on bulk density and porosity of diets were studied.  Results indicated that true density of the starter; grower and finisher diets were 1,442.574,...
