Question 1

Frequency of vibrations is usually expressed in

Accepted Answer

Frequency of vibrations is usually expressed in Hertz (Hz), which is equivalent to the number of cycles per second.

Question 2

The motion completed during one time period is known as _______.

Accepted Answer

A cycle refers to the complete motion that occurs during one time period in contexts such as oscillations or waves.

Question 3

Which of the following is a type of free vibration?

Accepted Answer

All three types, longitudinal, transverse, and torsional vibrations, can occur as free vibrations. Free vibrations happen when a system oscillates in response to an initial input and no external force is applied afterward.

Question 4

In a spring-mass system, which of the following force is not considered?

Accepted Answer

The answer of In a spring-mass system, which of the...

Question 5

The periodic time is given by _______.

Accepted Answer

The periodic time, often represented as the time taken for one complete cycle of a periodic motion, is given by the formula $T = \frac{2\pi}{\omega}$, where $T$ is the periodic time and $\omega$ is the angular frequency. This corresponds to choice B.
