4. (a) The following information about Ceramic A is given. Ceramic lons Atomic Mass Ionic Radius Electronegativity (g mol) (nm) (p) A Cation 24.31 0.072 1.31 Anion 16.00 0.140 3.44 (i) Explain the type of bondings that may be present primarily in Ceramic A (1) Predict the crystal structure of Ceramic A. ...6/- SULIT SULIT KIT 257 -6- Determine the density of Ceramic A in unit g cm? (b) ) (10 marks) Aluminium and iron have face centered cubic (FCC) and body centered cubic (BCC) structures, respectively. (0) Explain the reason aluminium is more ductile than iron. (ii) Explain the reason elasticity of modulus of a single crystal iron along (100) direction is lower than that along [111] direction. (6 marks) (c) C In order to achieve better fiber efficiency in a fiber reinforced composite, the practical optimal fiber lengths (Loptimum) are usually about 30 times of the critical fiber length (30 x Lcritical). Explain the rationale behind this statement (4 marks) Step by Step Solution
