7 0

Answer:

  • sailing ships were the primary means of maritime trade and transportation; exploration across the seas and oceans was reliant on sail for anything other than the shortest distances. Naval power in this period used sail to varying degrees depending on the current technology, culminating in the gun-armed sailing warships of the Age of Sail.

pav-90 [236]

Answer:

Technician B

Explanation:

When working on vehicles which are equipped with a catalytic coverter, the best practice of asphyxiating someone is to use carbon monoxide. This implies that you need an extraction sytem. Therefore, technician A is wrong by assuming no need of the system. In conclusion, technician B is correct.

A 4-pole, 3-phase induction motor operates from a supply whose frequency is 60 Hz. calculate: 1- the speed at which the magnetic
DiKsa [7]

Answer:

The answer is below

Explanation:

1) The synchronous speed of an induction motor is the speed of the magnetic field of the stator. It is given by:

n_s=\frac{120f_s}{p}\\ Where\ p\ is \ the \ number\ of\ machine\ pole, f_s\ is\ the\ supply \ frequency\\and\ n_s\ is \ the \ synchronous\ speed(speed \ of\ stator\ magnetic \ field)\\Given: f_s=60\ Hz, p=4. Therefore\\\\n_s=\frac{120*60}{4}=1800\ rpm

2) The speed of the rotor is the motor speed. The slip is given by:

Slip=\frac{n_s-n_m}{n_s}. \\ n_m\ is\ the \ motor\ speed(rotor\ speed)\\Slip = 0.05, n_s= 1800\ rpm\\ \\0.05=\frac{1800-n_m}{1800}\\\\ 1800-n_m=90\\\\n_m=1800-90=1710\ rpm

3) The frequency of the rotor is given as:

f_r=slip*f_s\\f_r=0.04*60=2.4\ Hz

4) At standstill, the speed of the motor is 0, therefore the slip is 1.

The frequency of the rotor is given as:

f_r=slip*f_s\\f_r=1*60=60\ Hz

1. It is known that there are some disadvantages in the casting of metal materials if the casting rate is high. Contrary to this
salantis [7]

Answer:

Some of the demerits or disadvantages of using a very slow castings rates in production of metal by the method of casting includes, with the solidification of metal, it may begin even before the mold is filled fully, which may result in defects such as shrinkage.

Secondly, the rate of slow casting will create castings that have a grain coarse structure that will affect the strength of the castings.

Explanation:

Solution

The disadvantageous of slow casting rates in the production of metals by casting method is explained below:

(1) The solidification of  metal may start even before the mold is filled completely, which may create or produce defects such as mis-runs and shrinkage  and shrinkage cavity.

So, the slow cavity rate will produce partial and incomplete castings

(2) Slow casting rate will produce castings which have a coarse grain structure which therefore affects the strength of the castings adversely.
