4.75cm * 5.22cm is 24.795cm²

but let's do this with m² instead:

0.0475m * 0.0522m = 0.0024795

now we can compare it with the 49780 much easier.

devide. that's the <u>roughly</u> 20,000,000fold of the plot, but it's still squared, so let's take the root

so the representative fraction is 1:4,480.

the exact value is in the screens

have a nice day:)

A solid shaft is subjected to an axial load P = 200 kN and a torque T = 1.5 kN.m. a) Determine the diameter of the shaft if the
Rom4ik [11]

Answer:

<em>a) 42 mm</em>

<em>b) 144.4 MPa</em>

<em></em>

Explanation:

Load P = 200 kN = 200 x 10^3 N

Torque T = 1.5 kN-m = 1.5 x 10^3 N-m

maximum shear stress τ = 100 Mpa = 100 x 10^6 Pa

diameter of shaft d = ?

From T = τ * \frac{\pi }{16} * d^{3}

substituting values, we have

1.5 x 10^3 = 100 x 10^6 x \frac{3.142 }{16} x d^{3}

d^{3} = 7.638 x 10^-5

d = \sqrt[3]{7.638 * 10^-5} = 0.042 m = <em>42 mm</em>

b) Normal stress = P/A

where A is the area

A = \frac{\pi d^{2} }{4} = \frac{3.142*0.042^{2} }{4} = 1.385 x 10^-3

Normal stress = (200 x 10^3)/(1.385 x 10^-3) = 144.4 x 10^6 Pa = <em>144.4 MPa</em>

A Carnot heat engine operates between 1000 deg F and 50 deg F, producing 120 BTU of work. What is the heat input to the engine?
Mazyrski [523]

Answer:

184.6 BTU

Explanation:

The thermal efficiency for a Carnot cycle follows this equation:

η = 1 - T2/T1

Where

η: thermal efficiency

T1: temperature of the heat source

T2: temperature of the heat sink

These temperatures must be in absolute scale:

1000 F = 1460 R

50 F = 510 R

Then

η = 1 - 510/1460 = 0.65

We also know that for any heat engine:

η = L / Q1

Where

L: useful work

Q1: heat taken from the source

Rearranging:

Q1 = L / η

Q1 = 120 / 0.65 = 184.6 BTU

1) When you invest in stock, what are you doing?
statuscvo [17]

<u>Explanation:</u>

1) When we invest in stock it means we are investing in long term investment. It includes risk factor also.

2) We can make money from stocks by retaining them for a long period and selling them when their price rises.

3) dividends are paid out of distributable profits. Some companies provide dividends regularly which act as a regular source of income for investors.

4) Capital gain is the benefit obtained on selling a capital asset and if we face loss on selling the capital asset it results in capital loss. Capital assets are like stock, bonds, properties, etc.
