Consider a cylindrical nickel wire 1.8 mm in diameter and 2.6 × 104 mm long. Calculate its elongation when a load of 290 N is ap

telo118 [61]

Answer:

e = 3.97*10^-4

Explanation:

1.8 mm = 0.0018 m

2.6*10^4 mm = 26 m

Elongation is The ratio between the stretched length and the original length.

e = L/L0

This is calculated with Hooke's law:

e = σ/E

Where

σ: normal stress

E: elastic constant

σ = P/A

Where

P: normal load

A: cross section

A = π/4 * d^2

Therefore:

e = P / (A * E)

e = 4 * P / (π * d^2 * E)

e = 4 * 290 / (π * 0.0018^2 * 207*10^9) = 3.97*10^-4

Westkost [7]

Since Tech B says that some airflow sensors use a hot wire to determine mass airflow he is the only one that is correct.

<h3>How does a mass airflow sensor work?</h3>

An MAF is one that consist of two sensing wires. One is known to be heated by the use of electrical current, while the other is not.

There are different kinds of wires for different kinds of purposes.

Tech A saying that mass airflow sensors determine mass airflow based on engine speed and manifold pressure is incorrect because that is not the role of the mass airflow sensors.

l

As air flows across the heated wire, it cools down. Hence, Since Tech B says that some airflow sensors use a hot wire to determine mass airflow he is the only one that is correct.

hram777 [196]

<h2>Corrected Question:</h2>

A step-up transformer has 26 turns on the primary coil and 720 turns on the secondary coil. If this transformer is to produce an output of 4100 V with a 16-mA current, what input current and voltage are needed?

<h2>Answer:</h2>

The input current and voltage needed are 443 mA and 148 V respectively.

<h2>Explanation:</h2>

In a step-up transformer, the relationship between the number of turns in its primary coil ( $N_{p}$ ), the number of turns in its secondary coil ( $N_{s}$ ), the input voltage ( $V_{p}$ ), the output voltage ( $V_{s}$ ), the input current ( $I_{p}$ ), and the output current ( $I_{s}$ ) is given by;
