Wave and Oscillation
♦ Compound Pendulum: any shape rigid body...
♦ Differential Equation for Simple Harmonic Motion:
(1) Force along the string =
(2) Force perpendiculer to the string =
The component balance the tension.
The Force active on the oscillating particle is,
We know,
The linear displacement,
Comparing equation (1) and (2),
Now using equation (1)
comparing with differential equation of SHM,
HW: Find out T for compound pendulum.
