Answer: True

Explanation: Piezoelectric pressure transducers are equipments that helps to generate voltage through the mechanical actions such as applied pressure. Piezoelectric transducer is made up of quartz crystals which are made of silicone and oxygen formed in a crystalline structure.

Piezoelectric transducer can also be described as a Piezoelectric sensor as it helps to detect electric voltage generated through applied pressure.

What are the three elementary parts of a vibrating system?

zhenek [66]

Answer:

the three part are mass, spring, damping

Explanation:

vibrating system consist of three elementary system namely

1) Mass - it is a rigid body due to which system experience vibration and kinetic energy due to vibration is directly proportional to velocity of the body.

2) Spring - the part that has elasticity and help to hold mass

3) Damping - this part considered to have zero mass and zero elasticity.

The equation sigma = My/l is used in the mechanics of materials to determine normal stresses in beams. When this equation is exp

Alenkinab [10]

Answer:

Part a : The SI unit of σ is Pascal.

Part b : The pressure is 414.28 psi.

Explanation:

Part a

The equation is given as

$\sigma =\frac{My}{l}$

As per the dimensional analysis

$M=[N-m]\\y=[m]\\l=[m^4]$

So the equation becomes

$\sigma =\frac{[N-m][m]}{[m^4]}\\\sigma =\frac{[N][m^2]}{[m^4]}\\\sigma =\frac{[N]}{[m^{4-2}]}\\\sigma =\frac{[N]}{[m^{2}]}\\$

As the dimensions are of pressure so the SI unit of σ is Pascal.

Part b

$\sigma =\frac{My}{l}\\\sigma =\frac{2000 \times 0.1}{7 \times 10^{-5}}\\\sigma =2857142.857 \, Pa$

Pressure in US customary base units is given in psi so

$1 Pa =1.45 \times 10^{-4}\\$

$\sigma =2857142.857 \times 1.45 \times 10^{-4} psi\\\sigma =414.28 psi$

So the pressure is 414.28 psi.

The volume fraction of particles in a WC-particle Cu-matrix CERMET is 0.84 Calculate the minimum expected elastic modulus, in GP

Lynna [10]

Answer:

the minimum expected elastic modulus is 372.27 Gpa

Explanation:

First we put down the data in the given question;

Volume fraction $V_f$ = 0.84

Volume fraction of matrix material $V_m$ = 1 - 0.84 = 0.16

Elastic module of particle $E_f$ = 682 GPa

Elastic module of matrix material $E_m$ = 110 GPa

Now, the minimum expected elastic modulus will be;

$E_{CT$ = ( $E_f$ × $E_m$ ) / ( $E_f$ $V_m$ + $E_m$ $V_f$ )

so we substitute in our values

$E_{CT$ = (682 × 110 ) / ( [ 682 × 0.16 ] + [ 110 × 0.84] )

$E_{CT$ = ( 75,020 ) / ( 109.12 + 92.4 )

$E_{CT$ = 75,020 / 201.52

$E_{CT$ = 372.27 Gpa

Therefore, the minimum expected elastic modulus is 372.27 Gpa

Nowadays power supply on board ship is determine low and high voltage. From what range low & high voltage is being determine

zlopas [31]

Any Voltage used on board a ship if less than 1kV (1000 V) then it is called as LV (Low Voltage) system and any voltage above 1kV is termed as High Voltage. Typical Marine HV systems operate usually at 3.3kV or 6.6kV.
