Abstract

The present study aimed to determine and recognize the physical ans mechanical properties as an important role in designing and developing of specific machines and their operations such as planting, harvesting and grading, Physical characteristics of corn kernels were obtained of two varieties: White Dent Corn single hybrid 10 (Corn 10), and yellow Dent Corn single hybrid 162,(Corn 162).For each of the physical characteristics, corn 10 gave the highest values comparing with corn 162. For each of the material surfaces, the galvanized surface gave the lowest static coefficient of friction (0.531 , 0.459)for corn 10 , corn 162  respectively;  and for the same group, the plywood surface gave the highest value (0.624 ,  0.586) for the two varieties respectively. For the painted surfaces, the oven - baked enamel processed  paint gave the lowest values (0.48, 0.5) for the two varieties comparing with Polish paint, Mutt paint, and untreated mild - steel  surfaces which gave (0.828, 0.72 – 0.72, 0.71 – 0.572, 0.549) respectively.
