Logarithmic Decrement Summary

The video tutorial explains the concept of logarithmic decrement, which is used to find the damping ratio in an underdamped system. It covers the derivation of the equation of motion for a spring mass damper system, showing how it results in a sine wave with exponentially decaying amplitude. The tutorial then labels the maximum displacements and defines the logarithmic decrement, providing an expression to calculate the damping ratio using this decrement.
