Round 1 - Technical 

(7 Questions)

  • Q1. How is antifrcition bearing differs from journal bearing
  • Ans. 

    Antifriction bearings use rolling elements to reduce friction, while journal bearings use a sliding motion.

    • Antifriction bearings use rolling elements like balls or rollers to reduce friction, while journal bearings use a sliding motion between the bearing surface and the shaft.

    • Antifriction bearings have lower friction and higher efficiency compared to journal bearings.

    • Examples of antifriction bearings include ball bear...

  • Q2. Write equation for modal analysis of rigid body ?
  • Ans. 

    Modal analysis of rigid body equation involves calculating natural frequencies and mode shapes.

    • Modal analysis involves determining the natural frequencies and mode shapes of a system.

    • The equation for modal analysis of a rigid body is typically represented as Kx = Mw^2x, where K is the stiffness matrix, M is the mass matrix, w is the angular frequency, and x is the mode shape vector.

    • The modal analysis equation helps in ...

  • Q3. What is mass matrix ?
  • Ans. 

    Mass matrix is a mathematical representation of the mass distribution of a system in structural dynamics.

    • Mass matrix is used in structural dynamics to represent the mass distribution of a system.

    • It is a square matrix that relates the accelerations of different points in a structure to the forces acting on those points.

    • The mass matrix is typically diagonal for systems with uniform mass distribution.

    • In finite element ana...

  • Q4. Explain about eigen values for free vibration ?
  • Ans. 

    Eigen values for free vibration represent the natural frequencies at which a system will vibrate without any external forces.

    • Eigen values are the values of natural frequencies at which a system vibrates without any external forces.

    • They are obtained by solving the characteristic equation of the system.

    • Each eigen value corresponds to a mode shape, which describes the pattern of vibration.

    • Higher eigen values indicate high...

  • Answered by AI
  • Q5. How do you derive frequency from free/forced vibrations ?
  • Ans. 

    Frequency can be derived from free/forced vibrations by analyzing the period of the vibrations.

    • Frequency is the reciprocal of the period of the vibration.

    • For free vibrations, the natural frequency of the system can be determined by analyzing the oscillations without any external force.

    • For forced vibrations, the frequency can be determined by analyzing the response of the system to an external force at different frequen...
