How does an increase in the radius of gyration of a compound pendulum affect its oscillation frequency_______________?
Show answer Hide answer
Answer: A. less
Explanation
A larger radius of gyration increases the mass moment of inertia of the compound pendulum. Higher inertia resists changes in rotational motion, slowing down the pendulum swing rate. Consequently, the oscillation frequency decreases while the time period increases correspondingly. Radius of gyration represents the radial distance to a point where mass is concentrated. Natural frequency of a pendulum is inversely proportional to the square root of inertia. Compound pendulums pivot about an axis rather than hanging from a single point.
Flywheel and pendulum designs require careful mass distribution to achieve desired oscillation timing. Mechanical timing devices and governors rely on accurate moment of inertia calculations. Structural vibration analysis considers radius of gyration to determine natural building frequencies. Stating frequency is more contradicts the inverse square root relationship with inertia. Equal frequency is impossible because changing the radius of gyration alters physical dynamics. Data is completely sufficient to determine the frequency change using pendulum equations.
