Bar Pendulum

Time Left:

1. What is the center of oscillation in a compound pendulum?

  • The point where the entire weight of the pendulum acts
  • The point at which a pendulum stops oscillating
  • The point where the pendulum is suspended from
  • The point where, if the entire mass were concentrated, the time period would remain unchanged

2. What defines the center of percussion of a pendulum?

  • The point where an impact does not cause a reactive force at the pivot
  • The point of maximum oscillation
  • The point where an impact causes maximum force at the pivot
  • The point at which the pendulum is suspended

3. What is the center of suspension in a pendulum?

  • The point where the pendulum is hung and oscillates about
  • The point where the pendulum's mass is concentrated
  • The point of maximum amplitude
  • The point of equilibrium in oscillatory motion

4. What is the center of mass of a body?

  • The point where the entire mass can be considered concentrated for translational motion
  • The point where all gravitational forces cancel out
  • The point from which the pendulum hangs
  • The geometric center of the object

5. How is the center of gravity best defined?

  • The point where the gravitational field is strongest
  • The same as the center of oscillation
  • The point where net torque is zero
  • The point at which the entire weight of the body acts for analyzing gravitational effects

6. Which of the following statements best explains why Kater's Pendulum is considered better than a Bar Pendulum for measuring gravity?

  • Bar Pendulum is more accurate because it has fewer components.
  • Kater's Pendulum eliminates the effects of air resistance and friction through knife-edge suspension and reversibility, leading to more accurate measurements.
  • Kater's Pendulum is better because it is simpler to construct and use.
  • Kater's Pendulum is shorter and lighter than a Bar Pendulum, making it easier to handle.

7. What defines a simple pendulum?

  • A pendulum with mass distributed along its length
  • A rigid body oscillating about a horizontal axis
  • A system of pendulums of varying lengths connected to a bar
  • A heavy particle suspended from a fixed support by a light inextensible string

8. Which of the following best describes a compound pendulum?

  • A particle suspended from a light string
  • A mass on a string swinging in a circular path
  • A rigid body oscillating about a horizontal axis in a vertical plane
  • A set of pendulums transferring energy to each other

9. What distinguishes a compound pendulum from a simple pendulum?

  • It oscillates in a horizontal rather than a vertical plane
  • It has mass distributed along its length and a moment of inertia
  • It swings faster than a simple pendulum
  • It uses a spring instead of a string

10. What is Barton’s Pendulum known for?

  • Being a rigid body with a fixed pivot point
  • Using a spring for its motion
  • Its oscillation in a conical path
  • Having multiple pendulums of varying lengths transferring energy through a common bar

11. What describes a conical pendulum?

  • A pendulum that oscillates in a straight line
  • A pendulum system used to transfer energy among multiple masses
  • A heavy particle on a rigid rod swinging back and forth
  • A mass on a string that swings in horizontal circles, tracing a cone

12. What is the principle of a bar pendulum?

  • It oscillates under the influence of restoring torque due to elasticity
  • It works on the principle of electromagnetic induction
  • It rotates continuously without any restoring force
  • It behaves like a compound pendulum and follows the laws of simple harmonic motion under gravity

13. What is the primary use of a bar pendulum?

  • To generate high torque in engines
  • To determine the acceleration due to gravity (g)
  • To measure electrical resistance
  • To convert mechanical energy into electrical energy
