1. A steel block with the dimensions of 25 cm (Thickness) x 50 cm (Width) x 100 cm (Length) is to carried by a metallic rod having a diameter of 10 mm and a length of 5 m. During this operation, only 3.5 mm elastic extension of the rod is allowed. (Density of steel 7.85 g/cm', 9.80665 N = 1 kg). (a) Which one of the followings is suitable as the rod material to carry this steel block? (b) How much load can be carried by the rod you determined in (a) before yielding?
