Question

The formula to calculate the angular frequency of a physical pendulum is ω = √{mgd/I}. What does the variable d represent?

A. The vertical component of the length of the physical pendulum

B. The length of the physical pendulum

C. The distance from the axis of rotation to the furthest point of the physical pendulum

D. The distance from the axis of rotation to the center of mass

Answer 1

The formula to calculate the angular frequency of a physical pendulum is ω = √{mgd/I}. What does the variable d represent?

A. The vertical component of the length of the physical pendulum

B. The length of the physical pendulum

C. The distance from the axis of rotation to the furthest point of the physical pendulum

D. The distance from the axis of rotation to the center of mass

1. Formula for angular frequency is w = √(mgL_cm/I )
2. Where m = mass of physical pendulum ,L_cm = distance of center of mass from suspension point ,I Moment of inertia about point of suspension
