fracture that occurs by rapid crack propagation and without appreciable macroscopic deformation.
The type of fracture that occurs by rapid crack propagation and without appreciable macroscopic deformation is called brittle fracture.
Brittle fractures typically happen in materials that lack significant plastic deformation capacity, such as ceramics and some brittle metals. When a brittle material is subjected to high stress or sudden impact, cracks can propagate rapidly through the material without any noticeable deformation. This type of fracture is characterized by a clean break surface, often with little or no plastic deformation, and is prone to occur in materials with high strength but low toughness. Examples of brittle fractures include glass shattering or a brittle ceramic breaking into pieces without any significant distortion.

draw a well labelled block diagram of a nuclear power station
Answer:
Here! I did an assignment about this a long time ago.
The roof of a house consists of a 22-cm-thick concrete slab (k = 2 W/m•K) that is 15 m wide and 20 m long. The emissivity of the outer surface of the iroof is 0.9, and the convection heat transfer coefficient on that surface is estimated to be 15 W/m2•K The inner surface of the roof is maintained at 15°C. On a clear winter night, the ambient air is reported to be at 10°C while the night sky temperature for radiation heat transfer is 255 K. Considering both radiation and convection heat transfer, determine the outer surface temperature and the rate of heat transfer through the roof. if the house is heated by a furnace burning natural gas with an efficiency of 85 percent, and the unit cost of natural gas is 51.20/therm (1 therm = 105.500 U of energy content), determine the money lost through the roof that night during a 14-hour period.
Answer:
Explanation:
Consider the outer surface of the roof to be \(T_{out}\)
Since, the heat conducted is equal to the sum of the heat transferred through convection and the rest by radiation
\(Q_{cond}=Q_{rad}+Q_{conv}\)
Rewrite the equation as follows
\(kA_s\frac{\Delta T}{L} =\epsilon \sigma A_s(T_s^4-T_{\infty}^4)+hA_s \Delta T\\\\k\frac{\Delta T}{L} =\epsilon \sigma (T_s^4-T_{\infty}^4)+h \Delta T\)
\(k\frac{T_{in}-T_{out}}{L} =\epsilon \sigma (T_{out}^4-T_{rad}^4)+h(T_{out}-T_{\infty})\)
subsititute
k = 2 W/m
\(15^o C=T_{in}\)
0.22 for L
\(0.9 = \epsilon\)
\(5.67\times 10^{-8}W/m^2.K^4=\sigma\)
\(255=T_{rad}\)
\(15W/m^2.K = h\)
\(10^oC=T_{\infty}\)
\(2\times \frac{15 -T_{out}}{0.22} =[0.9\times(5.67\times10^-^8)\times((T_{out}+273)^4-255^4)]+[15\times(T_{out}-10)]\\\\T_{out}=7.7^oC\)
Hence, the temperature of outer surface of the roof is \(T_{out}=7.7^oC\)
Calculate the surface area of the roof
\(A_s=b\times l\)
Here, b is the width , l is the length
substitute 15 for b , 20 for l
\(A_s=15 \times 20\\\\=300m^2\)
Write the equation for conduction
\(Q_{cond}=kA_s\frac{\Delta T}{L}\)
substitute 2W/m.K for k
\(300m^2 \ \ for \ A_s\\\\(15-7.7)^oC \ \ for \ \Delta T\\\\0.22m \ for \ L\)
\(Q_{cond}=2\times 300 \times \frac{15-7.7}{0.22}\\\\=19,000\)
Therefore, the total heat transferred through conduction is \(Q_{cond}=19,9009W\)
Consider the amount of natural gas required be R and the cost incurred in running the furnace through the night be M
\(R=\frac{Q_{cond}}{0.85} \times T\)
Duration of time T = 14 x 3600s
\(R=\frac{19909\times(14\times3600)}{0.85}kJ\\\\= \frac{19909\times(14\times3600)}{0.85\times105500}therm\\\\=11.2 \ therm\)
And the required money for the gas M = 11.2 x $1.2
= $13.44
Therefore, the money lost through the roof due to the heat transfer M=$13.44
You can split an integer N into two non-empty parts by cutting it between any pair of consecutive digits. After such a cut, a pair of integers A, B is created.
Your task is to find the smallest possible absolute difference between A and B in any such pair. If integer B contains leading zeros, ignore them when calculating the difference.
For example, the number N = 12001 can be split into:
A = 1 and B = 2001. Their absolute difference is equal to |1 − 2001| = 2000.
A = 12 and B = 001. Their absolute difference is equal to |12 − 1| = 11.
A = 120 and B = 01. Their absolute difference is equal to |120 − 1| = 119.
A = 1200 and B = 1. Their absolute difference is equal to |1200 − 1| = 1199.
In this case, the minimum absolute difference is equal to |12 − 1| = 11 for A = 12 and B = 001.
Write a function:
class Solution { public int solution(int N); }
that, given an integer N, returns the smallest possible absolute difference of any split of N.
Examples:
1. Given N = 12001, your function should return 11, as explained above.
2. Given N = 510, your function should return 5. The possible splits are:
A = 5 and B = 10, with the absolute difference equal to |5 − 10| = 5,
A = 51 and B = 0, with the absolute difference equal to |51 − 0| = 51.
The smallest possible absolute difference is 5.
3. Given N = 7007, your function should return 0. The smallest absolute difference can be achieved by splitting N into A = 7, B = 007.
In your solution, focus on correctness. The performance of your solution will not be the focus of the assessment.

The acceleration function of an object doing curvilinear motion is a = {(-0.2)i+2j+1.5k) m/s², where t is in s. If its initial velocity vo 8i m/s, and initial position is at the origin, determine the magnitude of its velocity when t = 3 s.
Answer:
the magnitude of the velocity when t = 3 s is 10.54 m/s.
Explanation:
To solve this problem, we can use the following kinematic equation that relates velocity, acceleration, and time:
v = vo + at
where:
v = final velocity
vo = initial velocity
a = acceleration
t = time
First, we need to find the velocity of the object at time t = 3 s. To do this, we can substitute the given values into the kinematic equation and solve for v:
v = vo + at
v = 8i + (-0.2i+2j+1.5k) x 3
v = 8i - 0.6i + 6j + 4.5k
v = 7.4i + 6j + 4.5k
The magnitude of the velocity is given by:
|v| = sqrt(vx^2 + vy^2 + vz^2)
where:
vx, vy, vz = the x, y, and z components of the velocity vector
Substituting the values from above, we get:
|v| = sqrt((7.4)^2 + 6^2 + (4.5)^2)
|v| = sqrt(54.81 + 36 + 20.25)
|v| = sqrt(111.06)
|v| = 10.54 m/s (approx)

Explanation:
An amplifier's input voltage is 12 mV, and its output voltage is 128 mV. Calculate voltage gain.
Answer:
Amplifier gain is equal to 10.67.
Explanation:
Voltage gain of an amplifier can be expressed as this equation:
A_v = (V_output) / (V_input)
Where A_v is the gain, V_output is the output voltage, and V_input is the input voltage.
For this we will solve:
A_v = 128 mV / 12 mV
A_v = 10.67
So the amplifier's gain is 10.67.

determine the required size of standard schedule 40 steel pipe to carry 192 m3/hour of water with a minimum velocity of 6.0m/sec
Answer:
Explanation:
To determine the required size of standard schedule 40 steel pipe to carry 192 m³/hour of water with a minimum velocity of 6.0 m/sec, we can use the following formula:
Q = A × v
where Q is the volumetric flow rate of water, A is the cross-sectional area of the pipe, and v is the velocity of water.
First, we need to convert the volumetric flow rate from m³/hour to m³/sec.
192 m³/hour = 0.0533 m³/sec
Next, we can rearrange the formula to solve for the cross-sectional area:
A = Q / v
A = 0.0533 m³/sec / 6.0 m/sec
A = 0.0089 m²
The cross-sectional area of the pipe is 0.0089 m².
Standard schedule 40 steel pipe has a nominal inside diameter (ID) of 1.049 inches, which is approximately 0.0266 meters. The cross-sectional area of the pipe can be calculated using the formula for the area of a circle:
A = π × (ID/2)²
A = 3.14 × (0.0266/2)²
A = 5.58×10^-4 m²
To determine the required size of the pipe, we can rearrange the formula for the area of a circle to solve for the diameter:
ID = 2 × √(A/π)
ID = 2 × √(0.0089/π)
ID = 0.106 meters
Therefore, the required size of standard schedule 40 steel pipe to carry 192 m³/hour of water with a minimum velocity of 6.0 m/sec is a nominal size of 4 inches, with an inside diameter of 0.102 meters (or 102 millimeters).

when applying an acrylic overlay, think of the nail as divided into how many zones?
Acrylic overlay is a popular technique used by nail technicians to give a protective layer to the natural nail or enhance the appearance of the nails. It involves applying a mixture of liquid and powder acrylic on the nails, which hardens to create a durable and long-lasting coating.
When applying an acrylic overlay, the nail is typically divided into three zones: the free edge, the stress area, and the nail bed. The free edge is the tip of the nail that extends beyond the fingertip, the stress area is the middle section of the nail that experiences the most pressure and tension, and the nail bed is the area closest to the cuticle. The free edge is the zone where the acrylic is applied the thinnest, usually just a thin layer of clear acrylic to protect the natural nail. The stress area is where most of the acrylic is applied, creating a thicker layer to provide strength and durability. The nail bed is the zone where the acrylic is applied the thickest, often in a light pink shade to create a natural-looking base for nail polish.
In conclusion, when applying an acrylic overlay, the nail is typically divided into three zones: the free edge, the stress area, and the nail bed. This division allows the nail technician to apply the acrylic in a way that provides maximum protection and durability while still creating a natural-looking finish.

A rope is wrapped three and a half times around a cylinder. Determine the range of force T exerted on
the free end of the rope for maintaining equilibrium that is required to just support a 5 kN weight. The
coefficient of friction between the rope and the cylinder is 0.2
The range of force exerted at the end of the rope is; 285.7 N to 1,000 N.
What is the Net horizontal force?The net horizontal force of the cylinder when it is at equilibrium position can be found by applying Newton's second law of motion. Thus;
∑F = 0
F - μF_n = 0
We are given;
F_n = 5 kN = 5000 N
μ = 0.2
Thus;
F - 0.2(5,000) = 0
F - 1,000 = 0
F = 1,000 N
The strength of the applied force will be increasing as the number of turns of the rope increases. Thus;
Minimum force = Total force/number of turns of rope
Since rope is wrapped three and half times, then;
number of turns = 3.5
Thus;
minimum force = 1,000/3.5
minimum force = 285.7 N
Thus, the range of force exerted at the end of the rope is 285.7 N to 1,000 N.

what is one of the determining factors which permits machine countersinking when flush riveting
One of the determining factors that permits machine countersinking when flush riveting is the thickness of the material being joined.
Machine countersinking is a process used in flush riveting, where a conical recess is created on the surface of a workpiece to accommodate the rivet head. This allows the rivet to sit flush with the surface, providing a smooth and aerodynamic finish. The ability to perform machine countersinking depends on various factors, and one crucial factor is the thickness of the material being joined.
When the material thickness is within a certain range, typically determined by the capabilities of the countersinking machine, machine countersinking becomes feasible. The machine is designed to remove a specific amount of material to create the countersink, and it needs sufficient material thickness to achieve the desired result.
If the material is too thin, there may not be enough material to form a proper countersink, resulting in weak joint integrity or potential damage to the material. On the other hand, if the material is too thick, it may exceed the capabilities of the machine, making it difficult or impossible to achieve a proper countersink.
Therefore, the thickness of the material being joined is a critical determining factor in determining whether machine countersinking can be successfully performed during flush riveting. It is important to consider the material thickness to ensure the proper application of machine countersinking for effective and reliable riveted joints.

Differentiation from first principle :
y = 7x
Formula to obtain derivative from first principle:
y'(x) = lim(h - - > 0) : [y(x + h) - y(x)] / h
Obtain : y(x + h)
y(x) = 7x
y(x + h) = 7(x + h)
Substitute into formula :
y'(x) = lim(h - - > 0) : [7(x + h) - 7x] / h
Expand :
y'(x) = lim(h - - > 0) : [7x + 7h - 7x] / h
y'(x) = lim(h - - > 0) : 7h/ h
y'(x) = 7
2.)
y = 5x³
y'(x) = lim(h - - > 0) : [y(x + h) - y(x)] / h
Obtain : y(x + h)
y(x) = 5x³
y(x + h) = 5(x + h)³
Substitute into formula :
y'(x) = lim(h - - > 0) : [5(x + h)³ - 5x³] / h
Expand :
y'(x) = lim(h - - > 0) : [5(x³ + 3x²h + 3xh² + h³) - 5x³] / h
y'(x) = lim(h - - > 0) : [5x³ + 15x²h + 15xh² + 5h³ - 5x³] / h
y'(x) = lim(h - - > 0) : [15x²h + 15xh² + 5h³] / h
