Question 1:The number of atoms per unit cell and the number of slip systems, respectively, for a facecentered cubic (FCC) crystal are
[ME 2018, Set-1]
No of atoms per unit cell in FCC ⇒
No. of slip systems in FCC are 12.
Question 2:The crystal structure of aluminium is
[ME 2017, Set-2]
Question 3:The material property which depends only on the basic crystal structure is
Question 4:Which of the following is the correct data structure for solid models?
Question 5:The effective number of lattice points in the unit cell of simple cubic, body centered cubic, and face centered cubic space lattices, respectively, are
For a simple cubic unit cell: 8 corners have 8 atoms and each atom at one corner contributes to 8 unit cells.
Therfore, answer is (1, 2, 4)
Question 6:The most widely used reinforcement in modern day FRP tennis racket is
Carbon fibre because of light weight.
