Answer 1

Answer:

Explanation:

Simple Harmonic Oscillations. Differential equation of SHM and its solution By Mr. G. K. Sahu Assistant Professor, CENTURION UNIVERSITY OF TECHNOLOGY AND MANAGEMENT, ODISHA . INTRODUCTION ... and fro motion about a mean position over the same path is called oscillation or vibration. Restoring force

Answer 2

mdt2d2x+bdtdx+kx=F0cosωt⟹dt2d2x+2βdtdx+ω02x=AcosωtThe expected solution is of form x=Dcos(ωt−δ)Put this is in above equation gives,tanδ=ω02−ω22βωFor resonant oscillation, ω0=ω⟹δ=π/2 which is the phase difference between x and F.
