     The board with the characteristic free \"electron cloud\".  Vander waals forces  convalent  iconic  metallic  The atomic bond that share electrons between atoms. Producces conductors,producces materials less dense than most mentals, and is common to cerramks is:  metallic  convalent  vander waals forces  inoic  Cold work is a process by which a metallic material is simultaneously deformed at room tamperature without ppreheating. It will result: incresing strengh and increasting ductillity.  increasing strength and decreasing ductillity.  decreasing strengh and incresing ductillity.   
  
  Solution
10. metallic bond
11.covalent bond
12 increasing strength and decreasing ductility
13.option d
14.option b
15.option b
16.true strain =ln(engineering strain +1)
=0.077
true stress= engineering stress*(engeering strain +1)
=3780psi
