A structural plate component of an engineering design must support 207 MPa in tension. If the aluminum alloy is used for this application,what is the largest internal flaw size that this material can support?Assume the shape factor is 1 and that for aluminum KIC=25. 6 MPa/m and yield strength is 455 MPa
Answers
The largest internal flaw size that this aluminum alloy can support is 113 μm.
The maximum allowable flaw size in a material is given by:
a = (KIC / (σ * π))²
where a is the maximum allowable flaw size, KIC is the fracture toughness, σ is the applied stress, and π is a constant.
Given the yield strength of the aluminum alloy as 455 MPa, the applied stress that the component can support in tension is 207 MPa. So, substituting the values into the above equation, we get:
a = (25.6 MPa/m / (207 MPa * π))²
a = 1.13E-7 m²
a = 113 μm
Therefore, the largest internal flaw size that this aluminum alloy can support is 113 μm.

A pipe 120 mm diameter carries water with a head of 3 m. the pipe descends 12 m in altitude and reduces to 80 mm diameter, the pressure head at this point is 13 m. Determine the velocity in the small pipe and the rate of discharge (in L/s)? Take the density is 1000 kg/m³.
Answers
Given:
- Diameter of the first pipe (D1): 120 mm = 0.12 m
- Diameter of the second pipe (D2): 80 mm = 0.08 m
- Head at the first pipe (H1): 3 m
- Altitude change (Δh): 12 m
- Head at the second pipe (H2): 13 m
- Density of water (ρ): 1000 kg/m³
Step 1: Calculate the velocities in the pipes using Bernoulli's equation.
Applying Bernoulli's equation between the two points in each pipe:
For the first pipe:
P1/ρ + V1²/2g + H1 = constant (1)
For the second pipe:
P2/ρ + V2²/2g + H2 = constant (2)
Since the pipes are open to the atmosphere, we can assume P1 = P2 = atmospheric pressure (approximately).
Simplifying equation (1):
V1²/2g + H1 = constant (3)
Simplifying equation (2):
V2²/2g + H2 = constant (4)
Step 2: Solve for the velocities V1 and V2.
Using equation (3) for the first pipe:
V1²/2g + 3 = constant (5)
Using equation (4) for the second pipe:
V2²/2g + 13 = constant (6)
Step 3: Solve for the velocities V1 and V2.
Since the constants in equations (5) and (6) are the same (as it is a continuous flow), we can equate the two equations:
V1²/2g + 3 = V2²/2g + 13
V1²/2g - V2²/2g = 10
(V1² - V2²)/(2g) = 10
V1² - V2² = 20g
V1² = V2² + 20g (equation 7)
Step 4: Convert the diameter to radius for each pipe.
r1 = D1/2 = 0.12/2 = 0.06 m
r2 = D2/2 = 0.08/2 = 0.04 m
Step 5: Calculate the rate of discharge (Q) using the continuity equation.
The continuity equation states that the product of the cross-sectional area (A) and the velocity (V) is constant in a flowing fluid.
Q1 = Q2 (since it is a continuous flow)
A1V1 = A2V2
πr1²V1 = πr2²V2
(r1²V1)/(r2²) = V2
Step 6: Calculate the velocity in the smaller pipe (V2).
Substitute the values in equation (7):
V1² = V2² + 20g
(V1²r2²)/(r1²) = V2²
(0.06²V2²)/(0.04²) = V2²
V2² = (0.06²V1²)/(0.04²) [Substitute V1² = 2g(3) from equation (5)]
V2² = (0.06² × 2g × 3)/(0.04²)
V2² = 0.27g
V2 = √(0.27g)
Step 7: Calculate the rate of discharge (Q) in L/s.

c) 37.65%
Explanation:
Given data:
condenser pressure ( P1 ) = 10 kPa ≈ 0.10 bar
saturated vapor pressure ( P2 ) = 18 MPa ≈ 180 bar
Net power output of cycle = 100 MW
attached below is detailed solution to the question
a) calculate mass flow rate of steam in Kg/h
applying the formula for calculating power
P = м ( h3 - h4 - h2 + h1 ) ------ ( 1 )
power ( p ) = 100 * 10^3 Kw
h3 = 2510.0
h4 = 1613.49

Designing an energy attenuation system that controls the 1200 kg car traveling at 100 km/hr at impact. Compare to design an energy attenuation system that controls the energy of a car at a fast speed.
Answers
Energy attenuation system is designed to control the kinetic energy of an object during an impact or collision to reduce the damage caused by the impact. When designing an energy attenuation system for a 1200 kg car traveling at 100 km/hr at impact, there are various factors that need to be considered.
The first factor is the speed of the car, which is 100 km/hr. The energy of the car can be calculated using the formula E = 0.5mv^2, where E is the kinetic energy, m is the mass of the car, and v is the velocity of the car. Therefore, the kinetic energy of the car can be calculated as follows: E = 0.5 x 1200 kg x (100 km/hr)^2= 3,333,333.33 JoulesTo control the energy of the car at impact, the energy attenuation system needs to absorb this energy gradually.
The faster the car is traveling, the higher the kinetic energy, and therefore, the more difficult it is to design a system that can control the energy of the car at impact. A car traveling at a fast speed requires a more advanced energy attenuation system, which can absorb the energy of the car gradually and reduce the force of the impact to safe levels.
In conclusion, designing an energy attenuation system for a car traveling at a fast speed requires a more advanced system than one for a car traveling at a slower speed. The system needs to be designed in such a way that it can absorb the energy of the car gradually, and the force of the impact is reduced to safe levels. The design of the system should ensure that the passengers are safe and are not exposed to any serious injuries.

how can the directed graph of a relation r on a finite set a be used to determine whether a relation is irreflexive?
Answers
A directed graph of a relation r on a finite set A can be used to determine whether a relation is irreflexive. In the case of an irreflexive relation, there are no loops in the graph, which means that no element in A is related to itself.
The directed graph of a relation r on a finite set A can be used to determine whether the relation is irreflexive. The directed graph can be drawn by placing the elements of A as vertices and drawing an arrow from a vertex i to a vertex j if i is related to j by r. If there is no arrow leading from a vertex i to the same vertex i, then the relation is irreflexive.
In conclusion, the directed graph of a relation r on a finite set A can be used to determine whether the relation is irreflexive. If there are no loops in the graph, which means that no element in A is related to itself, then the relation is irreflexive. By using this method, we can easily determine whether a relation is irreflexive without having to check every pair of elements in A.

Static Friction and Kinetic Friction
Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.
There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.
Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.
Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

The structure of a house is such that it loses heat at a rate of 5400 kJ/h per degree Cdifference between the indoors and outdoors. A heat pump that requires a power input of 6 kW isused to maintain this house at 21 C. Determine the lowest outdoor temperature for which the heatpump can meet the heating requirements of this house
Answers
Answer: Tl = - 13.3°C
the lowest outdoor temperature is - 13.3°C
Explanation:
Given that;
Temperature of Th = 21°C = 21 + 273 = 294 K
the rate at which heat lost is Qh = 5400 kJ/h°C
the power input to heat pump Wnet = 6 kw
The COP of a reversible heat pump depends on the temperature limits in the cycle only, and is determined by;
COPhp = Th/(Th - Tl)
COPhp = Qh/Wnet
Qh/Wnet = Th/(Th -Tl)
the amount of heat loss is expressed as
Qh = 5400/3600(294 - Tl)
the temperature of sink
( 5400/3600(294 - Tl)) / 6 = 294 / ( 294 - Tl)
now solving the equation
Tl = 259.7 - 273
Tl = - 13.3°C
so the lowest outdoor temperature is - 13.3°C

how many pairs of wires get switched when making a gigabit ethernet crossover cable
Answers
Answer:ALL FOUR PAIRS
Explanation: first major difference is the gigabit standards require the use of all four pairs (all eight wires), unlike Fast Ethernet which only utilizes two pairs of wires. As a result, in Gigabit Ethernet, all four pairs must be crossed when building a Crossover cable
When making a Gigabit Ethernet crossover cable, two pairs of wires get switched. Ethernet cables are used to connect computer networks that enable communication between different devices. The two most popular types of Ethernet cables are crossover and straight cables.
Ethernet cables use four pairs of wires to transmit data, out of which two pairs are utilized for transmitting and two pairs are used for receiving. In a straight-through Ethernet cable, the wire arrangement is identical at both ends. For this reason, a straight-through cable is employed to connect devices that belong to the same category. In contrast, a crossover Ethernet cable is employed to connect devices belonging to different categories. A crossover cable reverses the transmitting and receiving pairs, allowing the devices to communicate with one another. In a Gigabit Ethernet crossover cable, two pairs of wires are swapped or switched. These pairs are Pins 1-2 (White and Orange) and Pins 3-6 (White and Green). Therefore, we can conclude that two pairs of wires get switched when making a Gigabit Ethernet crossover cable.
