Acoustic greeting:
When ultrasonic waves travel from one end into the liquid medium and are reflected
Nodes in this medium from the other end and
Anti-nodes. The density of the liquid will be at most nodes and at least low.
Anti-nodes. The node will behave like an opaque region and the anti-nodes will behave
Like the transparent region. Now the liquid behaves as a diffraction grating and it is
Which is called sound greeting.
Sin (Theta) = N*(Lamda) --------(EQ.1)
where D is the distance between any two successive nodes or the antinodes of the resident
wave
Lambda is the wavelength of the monochromaticity.
If 'F' is the frequency of ultrasonic waves, then the speed of ultrasonic
Waves are given in liquid
Ultrasonic speed =frequency*wavelength
b = f*lambda(u) ----------(eq.4)
Subtract the value of lambda(u) in (eq.4)
Speed =F*N*Lambda/Sin (Theta)
Replacing the values of F, N, Lambda and Theta, the velocity of ultrasonic waves
Can be determined in liquidlike source of light
Theta is the angle of distortion
Let Lambda(U) be the wavelength of ultrasonic waves in a liquid medium, then
D=Lambda(U)/2
2D=Limda(U) -------(EQ.2)
Then (EQ.1) becomes,
Lamda (U)*Sin (Theta) = N*(Lamda)
Lamda(U) = N*Lamda/Sin (Theta) ---------(EQ.3)

Stress:
Praise:
The working force per unit area of the cross section of the wire is called
Tension.
stress =strength/territory =F/A
The unit for stress is n/m*m
Types of stress:
There are three types of pressure.
1) Longitudinal (OR) linear pressure.
2) Tshering (or) tangential tension.
3) Volume (or) bulk stress.
Strain:
Praise:
Change in content dimension and ratio of original dimension
It's called stress.
Tense=change in dimension/original dimension
Types of stress:
There are three types of stress.
1) Long-latitude stress (or) linear stress.
2) Strain in volume (or) bulk strain.
3) Lion strain (or) tangential strain.
What are the types of stress?
OA repeats the region. In region OA, Hooke's law is fully obeyed.
(5) Plastic area:
Stress and tension
(2) Shave (or) tangential tension.
As the tension increases, a point 'B' is bent. This point 'B'
(1) Longitudinal tension (or) line tension.
Approaching 'A' indicates the inflexion point.
The force acting on a given area of cross-section of the wire is called tension.

The region OP obtained by the material is the residue and is
The unit of stress is m*m/N.
The tension is reduced.
between tension and tension. This graph is called a cost-system diagram.
(4) Yield point and yield pressure:
Types of stress:
(1 proportional limit:
Strain = Change in dimension/original dimension
The stress increases from point 'C' and is called the yield point. Point 'C' is called the yield point and point 'D' is called the compression point.

What are the types of stress?
(2) Elastic limit and elastic region:
If the stress is gradually increased from point 'D' then the stress

(3) Volume (or) bulk.
(2) Volumes trine (or) Blastrite.
Stress:
Definition:
(3)shear strain (or) tangential strain.
(3) constants:
Tension = Force/Area A/F=
The ratio of change in material dimensions to original dimensions
The relationship between stress and strain is studied by making a graph.

This maximum failure force is called the ultimate strength (or) tensile strength.
(4) Effect of temperature
The unit size results in increased flexural properties.
(4) Effect of temperature:
In general, elasticity decreases with increasing temperature. This may be due to
As per point 'F'
When a material is subjected to a large constant stress (or) repeated no
During stress cycles, the elastic properties of the material gradually decrease.
Changes in temperature affect the elastic properties of materials.

Annealing is the process of heating the material to a certain temperature.
Increase in grain size with increase in temperature.
The material that breaks is called breaking stress.
