Answer:
The grinding machine is used for roughing and finishing flat, cylindrical, and conical surfaces; finishing internal cylinders or bores; forming and sharpening cutting tools; snagging or removing rough projections from castings and stampings; and cleaning, polishing, and buffing surfaces.
Since the armature is wave wound, the magnetic flux per pole is 0.0274 Weber.
<u>Given the following data:</u>
- Number of armature conductors = 144 slots
- Number of poles = 4 poles
- Number of parallel paths = 2
To find the magnetic flux per pole:
Mathematically, the emf generated by a DC generator is given by the formula;
× 
<u>Where:</u>
- E is the electromotive force in the DC generator.
- Z is the total number of armature conductors.
- N is the speed or armature rotation in r.p.m.
- P is the number of poles.
- A is the number of parallel paths in armature.
First of all, we would determine the total number of armature conductors:
×
× 
Z = 864
Substituting the given parameters into the formula, we have;
× 
× 
<em>Magnetic flux </em><em>=</em><em> 0.0274 Weber.</em>
Therefore, the magnetic flux per pole is 0.0274 Weber.

The number of hours that will be needed to charge a 600mah battery will be 1.5 hours.
<h3>
What is a battery?</h3>
It should be noted that an electric battery simply means a source of electric power that consist of one or more electrochemical cells that are with external connections that are important for powering electrical devices.
It should be noted that when a battery is supplying power, then the positive terminal is the cathode while the negative terminal is the anode.
In conclusion, the number of hours that will be needed to charge a 600mah battery will be 1.5 hours.

Answer:
Objective statements.
Explanation:
An objective statement can be defined as a short statement that explicitly states or describes what a person wants exactly or is looking out for in a particular item.
Objective statements are written to “maximize” or “minimize” a specific value associated with the product needs in order to define the goal or aim of the design process.
This ultimately implies that, objective statements are used by various manufacturing industries or companies to explicitly define the minimum or maximum requirements for the production of its goods.
