Generally, frictional losses are more predominant for the machines being not 100% efficient. This friction leads to the loss of energy in the form of heat, into the surroundings. Some of the supplied energy may be utilised to change the entropy (measure of randomness of the particles) of the system.
The advantages that can be associated to
drawings and symbols over written descriptions in engineering design and prototyping process are;
Communicate design ideas as well as technical information to engineers.
Symbols and drawings can be universal which means it is easy to interpret any where by professionals.
- An engineering drawing serves as complex dimensional object and symbol use by engineer to communicate.
- Drawings and symbols makes it easier to communicate design ideas and technical information to engineers and and how the process will go.
Therefore, drawings and symbols is universal to all engineer unlike written one.

Answer:
Explanation:
volume of 20.9 N
= 20.9 / 11.5 m³
= 1.8174 m³
In one hour 1.8174 m³ flows
in one second volume flowing = 1.8174 / 60 x 60
= 5 x 10⁻⁴ m³
Rate of volume flow = 5 x 10⁻⁴ m³ / s .
Answer:
Newton per square meter (N/m2)
Explanation:
Required
Unit of ultimate tensile strength
Ultimate tensile strength (U) is calculated using:
![U = \frac{Ultimate\ Force}{Area}](https://tex.z-dn.net/?f=U%20%3D%20%5Cfrac%7BUltimate%5C%20Force%7D%7BArea%7D)
The units of force is N (Newton) and the unit of Area is m^2
So, we have:
![U = \frac{N}{m^2}](https://tex.z-dn.net/?f=U%20%3D%20%5Cfrac%7BN%7D%7Bm%5E2%7D)
or
![U = N/m^2](https://tex.z-dn.net/?f=U%20%3D%20N%2Fm%5E2)
<em>Hence: (c) is correct</em>
