Made of high-strength steel, a tie rod is a slender cylindrical structure used to push (compression) and pull (tension) the front tires when the steering wheel is turning (Figure 2). The radius and length of the rod are r-5 mm and Lo=360 mm respectively. The Young's modulus of the steel is E=220 GPa and yield strength oy-350 MPa. To prevent the occurrence of plastic deformation, what is the maximum extension (4Lm) the steel rod can experience? a) 0.57 mm b) 0.159 % c) 1.71 mm d) 0.48x10-3 Section area A Figure 2 Force F A tie rod subjected to tensile loading Please select the FALSE statement a) In a crystalline metallic structure, the atoms are arranged in a three-dimensional array called a lattice. b) A BCC unit cell consists of eight atoms at the corners of a cube and one atom at the body centre of the cube. c) Hydrogen bond is a type of bond, which occurs due to the ease with which hydrogen atoms are willing to give up an electron to atoms of oxygen, fluorine, or nitrogen (x) d) FCC crystal structures are more close-packed than BCC crystal structures.
