Damping Ratio Question & Answers July 11, 2022 By WatElectronics This article lists 50 Damping Ratio MCQs for Engineering Students. The Damping Ratio Questions & Answers below include solutions and links to the relevant topic. This is helpful for users who are preparing for their exams and interviews, or professionals who would like to brush up on the fundamentals of the Damping Ratio. The damping ratio is denoted by the Greek symbol "Zeta". If 'zeta' is made zero then there is no opposition which means that oscillates with maximum frequency, as there is no opposition from the system then it oscillates naturally and freely. Hence, this frequency of oscillations under Zeta equal to zero condition is known as natural frequency. The dampings are of three types they are critical damping, over damping, and under damping. The damping that is required to stop the motion is known as critical damping, if the damping is less than required to remove the complete energy from the system is known as under damping. The damping which is more than required is known as critical damping. Every practical system takes a finite time to reach it's steady-state and during this period, it oscillates or increases exponentially. Every system has a tendency to oppose the oscillatory behavior of the system and this is called damping. The damping is measured by a factor known as the damping ratio and this factor explains how much dominant the opposition from the system to the oscillations in the output. Extensional deformation and shear deformation are the two ways to improve damping. 1). How many types of damping's are there? One Two Three Four None Hint 2).
