What is the function and role of product tear down charts, and how do engineers utilize them in the reverse engineering process?

lora16 [44]

Answer:

Product Teardown 28 pieces (1) Plastic packaging: protect and display product for purchase. (4) Exterior screws: hold case halves together. (1) Right case half: acts as part of a handle and contains the rest of the parts. (1) Left case half: acts as part of a handle and contains the rest of the parts.

Explanation:

A product teardown process is an orderly way to know about a particular product and identify its parts, system functionality to recognize modeling improvement and identify cost reduction opportunities. Unlike the traditional costing method, tear down analysis collects information to determine product quality and price desired by the consumers.

How much power would you need to cool down a closed, 1 Liter container of water from 100°C to 20°C in 5 minutes? (a) 1.1W (b)1.1

qaws [65]

Answer:

The power required to cool the water is 1.11Kw.

Hence the correct option is (b).

Explanation:

Power needed to cool down is equal to heat extract from the water.

Given:

Volume of water is 1 liter.

Initial temperature is 100C.

Final temperature is 20C.

Time is 5 minutes.

Take density of water as 100 kg/m3.

Specific heat of water is 4.186 kj/kgK.

Calculation:

Step1

Mass of the water is calculated as follows:

$\rho=\frac{m}{V}$

$1000=\frac{m}{(1l)(\frac{1m^{3}}{1000l})}$

m=1kg

Step2

Amount of heat extraction is calculated as follows:

$Q=mc\bigtriangleup T$

$Q=1(4.186kj/kgk)(\frac{1000 j/kgk}{1 kj/kgk})\times(100-20)$

Q=334880 j.

Step3

Power to cool the water is calculated as follows:

$P=\frac{Q}{t}$

$P=\frac{334880}{(5min)(\frac{60s}{1min})}$

P=1116.26W

or

$P=(1116.26W)(\frac{1Kw}{1000 W})$

P=1.11 Kw.

Thus, the power required to cool the water is 1.11Kw.

Hence the correct option is (b).

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;
