Answer:
Answer is explained in the explanation section below.
Explanation:
Solution:
Note: This question is incomplete and lacks necessary data to solve. But I have found the similar question on the internet. So, I will be using the data from that question to solve this question for the sack of concept and understanding.
Data Given:
x = 27 , 44 , 32 , 47, 23 , 40, 34, 52
y = 30, 19, 24, 13 , 29, 19, 21, 14
It is given that,
∑x = 299
∑y = 167
∑[tex]x^{2}[/tex] = 11887
∑[tex]y^{2}[/tex] = 3773
We are asked to verify the above values manually in this question.
So,
1. ∑x = 299
Let's verify it:
∑x = 27 + 44 + 32 + 47 + 23 + 40 + 34 + 52
∑x = 299
Yes, it is equal to the given value. Hence, verified.
2. ∑y = 167
Let's verify it:
∑y = 30 + 19 + 24 + 13 + 29 + 19 + 21 + 14
∑y = 169
No, it is not equal to the given value.
3. ∑[tex]x^{2}[/tex] = 11887
Let's verify it:
For this to find, first we need to square all the value of x individually and then add them together to verify.
∑[tex]x^{2}[/tex] = [tex]27^{2}[/tex] + [tex]44^{2}[/tex] + [tex]32^{2}[/tex] + [tex]47^{2}[/tex] + [tex]23^{2}[/tex] + [tex]40^{2}[/tex] + [tex]34^{2}[/tex] + [tex]52^{2}[/tex]
∑[tex]x^{2}[/tex] = 11,887
Yes, it is equal to the given value. Hence, verified.
4. ∑[tex]y^{2}[/tex] = 3773
Let's verify it:
Again, for this we need to find the squares of all the y values and then add them together to verify it.
∑[tex]y^{2}[/tex] = [tex]30^{2}[/tex] + [tex]19^{2}[/tex] + [tex]24^{2}[/tex] + [tex]13^{2}[/tex] + [tex]29^{2}[/tex] + [tex]19^{2}[/tex] + [tex]21^{2}[/tex] + [tex]14^{2}[/tex]
∑[tex]y^{2}[/tex] = 3,845
No, it is not equal to the given value.

A crystalline grain of aluminum in a metal plate is situated so that a tensile load is oriented along the [1 1 1] direction. What tensile stress is required (to 3 significant figures) to produce a critical resolved shear stress of 0.242 MPa along [1 0 1] in the (1 1 -1) plane
Answer: required tensile stress is 0.889 MPa
Explanation:
Given that;
tensile load is oriented along the [1 1 1] direction
shear stress is 0.242 MPa along [1 0 1] in the (1 1 -1) plane
first we determine
λ which is Angle between [1 1 1] and [1 0 1]
so
cosλ = [ 1(1) + 1(0) + 1(1) ] / [ √(1² + 1² + 1²) √(1² + 0² + 1²)]
= 2 / √3√2 = 2/√6
Next, we determine ∅ which is angle between [1 1 1] and [1 1 -1]
so,
cos∅ = [ 1(1) + 1(1) + 1(-1) ] / [ √(1² + 1² + 1²) √(1² + 1² + (-1)²)]
cos∅ = [ 2-1] / [√3√3 ]
cos∅ = 1/3
Now, we know that;
σ = T_stress/cosλcosθ
so we substitute
σ = 0.242 / ( 2/√6 × 1/3 )
σ = 0.242 / 0.2721
σ = 0.889 MPa
Therefore, required tensile stress is 0.889 MPa
A certain power-supply filter produces an output with a ripple of 100 mV peak-to-peak and a dc value of 20 V. The ripple factor is
Answer: the ripple factor is 0.005
Explanation:
Given the data in the question;
we know that expression of ripple factor is;
r = Vr(pp) / Vdc
where Vr(pp) the peak to peak is ripple voltage ( 100mv = 0.1 V)
and Vdc is the dc value of the filter output voltage ( 20 V)
so we substitute our given values;
r = 0.1 / 20
r = 0.005
Therefore; the ripple factor is 0.005
The ripple factor of the given power supply filter is; γ = 0.005
We are given;
Ripple peak to peak voltage; V_r,pp = 100 mV = 0.1 V
DC value of the filter output voltage; V_dc = 20 V
Now, formula for the ripple factor is given as;
γ = V_rms/V_dc
Now, our ripple peak to peak voltage is also known as the rms value of ripple voltage at the output. Thus;
γ = 0.1/20
γ = 0.005

Water is a great eroder. Man-made levees must be tough. They are often built of
A. rock and concrete.
B. packed mud and dirt.
C. sandbags and gravel.
Water is a great erode. Man-made levees must be tough. They are often built of rock and concrete. The correct option is A.
What are Man-made levees?Man-made levees are designed to withstand the erosive power of water and prevent flooding in areas near bodies of water.
As such, they are constructed using strong and durable materials, such as rock and concrete, that can resist the forces of water and prevent erosion.
These materials provide a solid and stable foundation for the levees, which is important for ensuring their effectiveness in protecting against flooding.
Packed mud and dirt or sandbags and gravel may not provide sufficient strength and durability to withstand the erosive power of water and may not be suitable for building effective levees.
Thus, the correct option is A.

At what angle should you place your elbows while at your workstation? Above 120 degrees At 60 degrees Below 90 degrees Between 90 and 110 degrees
Answer:
Between 90 and 110 degrees
Explanation:
Ideally, the angle should not be less than 90° so that your elbows could be parallel to the workstation. This will in turn mean that the shoulders will be relaxed and it will make it a lot less stressful to keep the wrists in a straight manner.
Looking at the options, there is no exact figure of 90°, however, it could be between 90° to 110° because the difference is not going to be much in terms of making the shoulders relaxed.
Answer:
90 degrees i did the test and i also looked it up to make sure i was right.

An aluminum bar 125 mm long with a square cross section 16 mm on an edge is pulled in tension with a load of 66,700 N and experiences an elongation of 0.43 mm. Assuming that the deformation is entirely elastic, calculate the modulus of elasticity of the aluminum. (Please leave a space between the number and the unit, and use correct capitalization and lower case for units - for example: MPa, not Mpa.)
Answer: the modulus of elasticity of the aluminum is 75740.37 MPa
Explanation:
Given that;
Length of Aluminum bar L = 125 mm
square cross section s = 16 mm
so area of cross section of the aluminum bar is;
A = s² = 16² = 256 mm²
Tensile load acting the bar p = 66,700 N
elongation produced Δ = 0.43
so
Δ = PL / AE
we substitute
0.43 = (66,700 × 125) / (256 × E)
0.43(256 × E) = (66,700 × 125)
110.08E = 8337500
E = 8337500 / 110.08
E = 75740.37 MPa
Therefore, the modulus of elasticity of the aluminum is 75740.37 MPa

Recent research has identified mold-surface textures that will either (a) inhibit a solidified steel from separating from the mold or (b) force it to stay in contact in continuous casting. What is the advantage of a mold that maintains intimate contact with the steel
Answer:
faster heat conduction
Explanation:
The advantage of mold that maintains intimate contact with the material is that thermal contact resistance between the two is going to be reduced. That is, it would be lower.
Consequently, what would be happening would be heat getting conducted faster, this would then allow for higher traverse speeds or it could allow for the usage of shorter molds.

Describe the differences between case hardening and through hardening, insofar as engineering applications of metals are concerned.
Answer:
The answer is below
Explanation:
Case hardening is a form of steel hardening that is applied on mild steel with a high temperature of heat.
It results in material forming a hard surface membrane, while the inner layer is soft.
It is mostly used for universal joints, construction cranes, machine tools, etc.
On the other hand, Through hardening is a form of steel hardening in engineering that involves heat treatment of carbon steel.
It increases the hardness and brittleness of the material.
It is often used for axles, blades, nuts and bolts, nails, etc.
