Question

a. The number of cycles per unit time is called the period of oscillation T F b. Raylight's energy method can be luseod for conservative systems with harmonuic motion T F c. What is the relation between the damped natural frequency, wa, natural frequency, wn, and damping ratio, ? d. What is the equation of motion of a mass-spring system? e. A system is calledstable, if its free-vibration response neither grows nor decays, but remain constant or pure oscillatory as time approaches infinity f. The natural frequency of the system is unaltered with the addition of Coulomb damping, while it is reduced with addition of viscous damping. T F g. The equivalent stiffness of two parallel springs with stifhoss ki and k2 is equal to: ko = ki + k2

Explanation / Answer

ACCORDING TO THE CHEGG GUIDELINES I AM ALLOWED TO ANSWER ONLY (FIRST ) ONE QUESTION AT A TIME.

A) The number of cycles per unit time is called period of oscillations ( STATEMENT IS FALSE ) FALSE

Reasoning : The no of cycles per unit time is called FREQUENCY

PERIOD IS THE TIME TAKEN TO COMPLETE ONE CYCLE.
