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 *
* 
substituting values, we have
1.5 x 10^3 = 100 x 10^6 x
x 
= 7.638 x 10^-5
d =
= 0.042 m = <em>42 mm</em>
b) Normal stress = P/A
where A is the area
A =
=
= 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>
The train is traveling 26 meters A second .
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
<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.
