Question Paper
A steel specimen shows upper yield point at 210 MPa and lower yield point at 200 Mpa. If modulus of elasticity, E for steel is 210 x 10^3 MPa, calculate modulus of resilience.
Describe the procedure for finding Rockwell hardness.
Classify plain carbon steels. Describe the applications of low, medium and high carbon steels.
What are brasses and bronzes? What is hydrogen embrittlement of copper and how can it be avoided
What is insulator Describe the various types of insulators.
Describe the properties of vitrified, resinoid and rubber bonding.
How are composite cylinders and tubes manufactured?
A composite is made of alternate layers of 60% E-glass and 40% epoxy resin. If moduli of elasticity of E-glass and epoxy are 72 GPa and 3 GPa respectively, find the modulus of elasticity of the laminated composite under isostrain and isostress conditions. Show loading on sketch.
An edge cracked beam carries crack in its central plane whose length is 5 mm. A load of 1000 N is applied opposite to the crack, so that the crack would tend to open in bending. Calculate the stress intensity factor of crack, if the beam has the following dimensions
W=25m,B =10mm,S =100mm
Explain the cleavage and shear fracture at atomistic level.
Describe the various techniques for providing surface protection to wear.
What are the different methods of surface treatment?
What is Moh's hardness scale Why ,is it difficult to measure hardness of steel on Moh's scale?
Differentiate between Annealing and Process Annealing.
Define functionality of Monomer.
Give classification of Lubricants.
