Question

describe states of oscillation for phase angle 1100 degree​

Answer 1

Explanation:

Phase angle is the angle turned by the radius vector from the starting position

Explanation:

Consider a particle vibrating in Simple Harmonic Motion (SHM). Phase (in SHM) is defined as the state of a particle pertaining to its position and direction of motion.

Now, the phase angle concept is as below.

A particle vibrating in SHM has its corresponding circle of reference. To know the phase angle, we need to affix starting position of radius vector at that moment when particle executing SHM is on the verge of crossing mean position.

Please refer to the attached picture for the diagram.

This is the circle of reference for the particle in SHM. Position A is the initial position of the radius vector. At positions B,C,D, etc. the radius vector has turned through angles π/4, π/2, 3π/4...respectively.

We find that all the angles mentioned above can be expressed uniquely as a fraction of 2π.

Phase angle is the angle turned by the radius vector from the starting position. So phase of particle at positions A, B, C can be assigned as 0 (or 2π) , π/4, π/2... and so on.

Answer 2

The oscillation regions of the 1100 degree angle are:

• Oscillation is a recurring variation, usually over time.

• It is measured between two or more different conditions or in terms of equity or in terms of average value.

• Other common examples of oscillations include the current and simple pendulum.

• The oscillating foils that produce thrust-oscillating are processed using power and energy measurements, as well as visual data, to distinguish the main features of the surrounding flow and foil tracking.

• Visual data are obtained using digital particle velocimetry at Reynolds 1100, and power and energy data are measured at Reynolds number 40,000.
