physical and mechanical properties of alfalfa (medicago sativa, l.) grind are required for optimum design of equipment used in transporting, processing and storage of the material. this study was conducted to determine the effect of particle size (2.38, 3.36 and 4.76 mm) and moisture content (8, 9.3 and 11% wb) on some physical and mechanical properties of alfalfa grind. these properties includ...

one of the main factors that cause to quality loss for fresh fruit market apples is bruise damage. amongst the factors that affect apple sensitivity to bruising, major one is drop height and area profile during the impact. in the present study, four iranian apple varieties consisted of atirli, kapak, kowse and paiez that were selected and 100 fruits of each variety were picked up, then apples w...

the influence of surface roughness magnitude and direction on dry static friction coefficient between two similar steel samples has been studied through an experiment. a testing apparatus has been designed and fabricated to measure the friction coefficient for a few forms of surface asperity. according to the results of the experiments, dry friction coefficient is affected by both magnitude and...

in this article, the size, dimensions, volume, bulk and particle densities, empyting and filling angles of repose and friction coefficients against different surfaces were evaluated for two varieties of barley, sahra and valfajr, as a function of moisture content in the range of 10.12 to 42.17 (w.b.%). most physical properties of barley varieties were significantly affected by moisture content ...
