Answer:
T = 15 kN
F = 23.33 kN
Explanation:
Given the data in the question,
We apply the impulse momentum principle on the total system,
mv₁ + ∑
= mv₂
we substitute
[50 + 3(30)]×10³ × 0 + FΔt = [50 + 3(30)]×10³ × ( 45 × 1000 / 3600 )
F( 75 - 0 ) = 1.75 × 10⁶
The resultant frictional tractive force F is will then be;
F = 1.75 × 10⁶ / 75
F = 23333.33 N
F = 23.33 kN
Applying the impulse momentum principle on the three cars;
mv₁ + ∑ = mv₂
[3(30)]×10³ × 0 + FΔt = [3(30)]×10³ × ( 45 × 1000 / 3600 )
F(75-0) = 1.125 × 10⁶
The force T developed is then;
T = 1.125 × 10⁶ / 75
T = 15000 N
T = 15 kN
Its 0.001
0.01 x100 = 1mm
0.001x100=0.1mm
0.1=10mm
1m
ANSWERS:
Explanation:
Given:
Piston cylinder assembly which mean that the process is constant pressure process P=C.
<u>AMMONIA </u>
state(1)
saturated vapor 
The temperature 
Isothermal process 
a)
( double)
b)
(reduced by half)
To find the final state by giving the quality in lbf/in we assume the friction is neglected and the system is in equilibrium.
state(1)
using PVT data for saturated ammonia
then the state exists in the supper heated region.
a) from standard data
assume linear interpolation
b)
from standard data
then the state exist in the wet zone
The professional ethics for computer engineers are:
- They will Contribute to society and to human well-being.
- They will Avoid harm.
- Be honest and trustworthy.
- They will be fair and take action that do to discriminate others.
<h3>What are the Characteristics of Code of Ethics?</h3>
The code of ethics are known to be a kind of a universal moral values, that is one that state that what a person expect of any given employee such as been trustworthy, respectful, responsible, and others.
Note that Rules of Practice, Professional Obligations and Codes of Ethics. are known to be put in place to avoid issues that may lead to conflict.
Therefore, i believe that As Engineering and Computing students, the respective professional bodies, Rules of Practice, Professional Obligations and Codes of Ethics are good and acts as a check and balance to us.
Therefore, The professional ethics for computer engineers are:
- They will Contribute to society and to human well-being.
- They will Avoid harm.
- Be honest and trustworthy.
- They will be fair and take action that do to discriminate others.
