Question

Example 5.7: Describe the state of
oscillation if the phase angle is 1110°.​

Answer 1

Explanation:

ω=2πT where T is the period of the oscillation. If you have two oscillations an oscillation A has a maximum displacement at time tA and oscillation B reaches a maximum displacement at a time tB then the phase angle ϕBA can be said to be tB−tAT⋅2π where T is the period of the motion.
