Answer:
Explanation:
Using the proper technique is incredibly important because it prevents the materials being joined from breaking and/or causing an accident. If the wrong joining technique is used the materials may not hold in place and come apart easily instead. Also, some joining techniques are not meant for some materials and may instead cause the material to become weak and brittle causing it to break apart almost immediately.
Joining describes a technique which is used to merge two or more independent materials together. The use of wrong joining technique or procedure could result in accident.
In engineering construction, the need to join materials together is always needed for so many reasons. Hence, depending on the materials to be merged, welding, soldering and some other techniques may be employed.
Therefore, wrong or inadequate joining may cause these parts to split or breakup, hence causing severe casualty.

A farmer wants to buy a 10 kg bag of fertilizer (organic soil). They have the choice between two merchants. Merchant A sells the 10 kg bag for $10 and the bag indicates that the fertilizer is completely dry. Merchant B sells the 10 kg bag for 8$, and the bag indicates that the fertilizer has a water content of 20%. If the farmer can only use the solid constituents of the bag, which merchant has the better deal?
Answer:
Since the farmer wants to buy a 10 kg bag of fertilizer, he should buy it from merchant A. However, Merchant A and B are selling at the same price for a unit value. In other words, Both Merchant A and B are selling 1kg of dry fertilizer for $1.
Explanation:
Which merchant has the better deal means which merchant offers the farmer a better deal.
For Merchant A, 10 kg bag = $10
meaning it contains a real 10 kg bag of dry fertilizer which the farmer can use without losing any Kg to drying.
While for Merchant B, 10 kg bag = $8
where the 10kg = 80% dry fertilizer + 20% water content
But the farmer can only use the solid constituents of the bag which means,
Merchant B is giving 80/100 x 10Kg of dry fertilizer for $8
That is, 8kg for $8
Since the farmer wants to buy a 10 kg bag of fertilizer, he should buy it from merchant A. However, Merchant A and B are selling at the same price for a unit value. In other words, Both Merchant A and B are selling 1kg of dry fertilizer for $1.

1. The hull of the space shuttle consists of ceramic tiles bonded to an aluminum skin. Discuss the design requirements of the shuttle hull that led to the use of this combination of materials. What problems in producing the hull might the designers and manufacturers have faced
Answer:
Follows are the solution to the given question:
Explanation:
In the environment of the piles of earth, its spacecraft faces extreme temperatures:
Therefore, to prevent satellite build sustainability, a temperature control system must be used.
Its skin must be rather permeable in physiological terms.
Its shuttle's surface should have adhered to both the material well.
Whether it gets broken, it ought to be easy to repair.
All tile mostly on the cutter is composed of silicon dioxide particles, that are bonded and create a tile of very low density.
Its heat transfer is so small that even a person may hold a burning hot side on one side of the tile.
Skin that uses a rubber resin to ensure that perhaps the powers may not release the cutting that heat-treated will then the internal body.
The design requirements that led to the combination of ceramic tiles and aluminium materials for the hull of shuttle space are; discussed below.
The space shuttle experiences extreme temperatures during re-entry into the earths atmosphere. Thus, as a result, a thermal protection system must be provided to help prevent damage of the shuttle structure.
Therefore, the skin must be made up of material that has an exceptionally low thermal conductivity and also the material must be able to be firmly attached to the skin and also be able to be easily repaired in case of any damage.
Secondly, the tiles used on the space shuttle will have to be composed of silica fibers that are bonded together to generate a ceramic of low density. The thermal conductivity of the ceramic would have to be low such that if you touch one end while the other is very hot, you will not feel the hotness.
Now, the tiles will be attached to the shuttle skin with the aid of a rubbery polymer which ensures that the forces don't break the tile loose which will then expose the underlying skin to high temperatures.

The doorbell of a home requires 10 volts to operate. A transformer is used to connect a 120 v primary circuit within the home to the doorbell. The transformer in the doorbell has 500 turns on the primary coil and supplies the doorbell with 900 mA of current.
Required:
a. Determine whether the transformer features a step-up or step-down design.
b. Calculate the number of turns on the secondary coil.
c. Calculate the current that is drawn from the 120-V household circuit to operate the doorbell in mA.
Answer:
See explanation
Explanation:
a) The transformer must be a step down transformer because the secondary voltage which it supplies is less than the primary voltage.
b) From;
Ns/Np = Es/Ep
Where;
Ns= number of turns in secondary coil
Np= number of turns in primary coil
Es= voltage in secondary coil
Ep= voltage in primary coil
NsEp = EsNp
Ns = EsNp/Ep
Ns = 10 * 500/120
Ns = 42 turns
c) From;
Es/Ep = Ip/Is
EsIs = EpIp
Ip = EsIs/Ep
Ip = 10 * 900 * 10^-3/120
Ip = 75 mA

____________ are calibrated to deliver one fixed volume and are ____________ than ______________. Select one: a. Transfer pipets; less accurate; measuring pipets b. Transfer pipets; more accurate; measuring pipets c. Measuring pipets; more accurate; transfer pipets d. None of these answers is correct. e. Measuring pipets; more precise; transfer pipets
Answer:
b. Transfer pipets; more accurate; measuring pipets.
Explanation:
Transfer pipets can be defined as an ungraduated or graduated disposable plastic instrument which are typically used in science laboratories to transfer or deliver liquids that are small in volume (microliters) . Also, they are generally being referred to as chemical
droppers, teat pipets, eye droppers, pasteur pipets, or droppers. It is made up of an ultra-clear long, slender tube with low density polyethylene (LDPE) and an integral molded bulb. The molded bulb allows a fixed volume of the desired liquid to be dispensed (transfered) or aspirated through compression and relaxation.
Hence, transfer pipets are calibrated to deliver one fixed volume and are more accurate than measuring pipets because of its long, slender tube which limits errors.
Transfer pipets are measurement pipets since they are calibrated to provide a specific volume.
Transfer pipets and Measuring pipets
Transfer pipets have been ungraduated as well as graded disposable plastic instruments that were already commonly used during research labs to transmit as well as distribute small-volume liquids.
Combining compression as well as relaxation, the molded bulb permits a set volume of such necessary fluid material to be administered as well as inhaled.
Thus the response above is correct.

An electrical device is insulated on all sides except one face. That face is bonded to a 4mm thick aluminum plate which is cooled by air. The electrical device dissipates 10^4 W m2 The resistance of the joint between the device and aluminum plate is 0.5E-4 m2K W The conductivity of the aluminum is 238 W mK The temperature of the air is 278 K and the convection coefficient from the aluminum plate to the air is 100 W m2K What is the operating temperature of the device
Answer:
t₁ = 378.668 K
Explanation:
From the given information:
The heat dissipated (q) from the electrical device = [tex]10^4 W/m^2[/tex]
The contact resistance between device and aluminium;
(R_{const} ) = 0.5× 10⁻⁴ m² K/W
Conductivity of aluminum (k) = 238 \ W/mK
The thickness of aluminum plate (L) = 0.004 m
Convection coefficient (h) = 100 \ W/m^2 K
Surrounding temperature (t_2) = 278 \ k
According to Fourier's law of heat conduction.
[tex]q = \dfrac { t_1- t_2 }{R_{const} + \dfrac{L}{k} + \dfrac{1}{h} }[/tex]
[tex]10^4 = \dfrac{t_1 - 278}{0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100} }[/tex]
[tex]10^4 *( 0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100}) = t_1 - 278[/tex]
[tex]100.668 = t_1 -278[/tex]
t₁ = 378.668 K
