Classify the different ceramic materials. Write basic properties of the ceramic

materials along with their applications. Explain the glass sheet forming process

with neat figure and narrate its advantages.

Explain the principle of capacitance with neat sketch. derive the equation of

capacitance and mention its applications.

A large plate of a glass is subjected to a tensile stress of $40$ MPa $.$ If the specific

surface energy and modulus of elasticity for this glass are $0\mathrm{.}3\frac{J}{m^2}$ and $69$ GPa $,$

respectively. Determine the maximum length of a surface flaw that is possible

without fracture.

A brass rod is to be used in an application requiring its ends to be held rigid. If the

rod is stress free at room temperature $20C,$ what is the maximum temperature to

which the rod may be heated without exceeding a compressive stress of $172$ MPa $?$

Assume a modulus of elasticity of $100$ GPa for brass.

a$)$ What are the different types of corrosionsexplain with neat sketches? Explain the

different methods of reducing the corrosions?

b$)$ A continuous and aligned glass fiber$-$reinforced composite consists of $40$vol$\%$ of

glass fibers having a modulus of elasticity of $69$ GPa and $60$vol$\%$ of a polyester

resin that, when hardened, displays a modulus of $3\mathrm{.}4$ GPa $.$ If the cross$-$sectional

area is $250m{m}^2$ and a stress of $50$ MPa is applied in this longitudinal direction,

compute the magnitude of the load carried by each of the fiber and matrix phases.

Determine the strain that is sustained by each phase when the stress in this

composites plate?
