MECHANICAL ENGINEERING JOB INTERVIEW QUESTIONS:-
1.)Mention two types of dislocations.
Ans: Dislocation refers to a break in the continuity of the lattice. In edge dislocation, one plane of atoms gets squeezed out. In screw dislocation the lattice atoms move from their regular ideal positions.
2.)What is Curie point ?
Ans: Curie point is the temperature at which ferromagnetic materials can no longer be magnetized by outside forces.
3.)What is the difference between proof resilience and modulus of resilience ?
Ans: Proof resilience is the maximum strain energy that can be stored in a material without permanent deformation. Modulus of resilience is the maximum strain energy stored in a material per unit volume.
4.). What is the difference between column and strut ?
Ans: Both column and strut carry compressive load. Column is always vertical but strut as member of structure could carry axial compressive load in any direction.
