An AISI 1018 steel has a yield strenght, Sy = 295 MPa. Using the distortion-energy theory for the following given state of plane stress, determine the factor of safety. Write your final answer in two decimal places. σx =−89MPa, σy = 40MPa, τxy = 0 Hints: For distortion energy theory: σ′ = (σₓ² − σₓσᵧ + σᵧ² + 3rₓᵧ²)¹/²
n = Sy/σ'
Answers
To determine the factor of safety using the distortion-energy theory, we need to calculate σ' and then find the factor of safety (n) using the formula n = Sy/σ'.
Given:
σx = -89 MPa
σy = 40 MPa
τxy = 0
First, we need to calculate σ':
σ' = (√(σx² - σxσy + σy² + 3τxy²))
Substituting the given values:
σ' = (√((-89)² - (-89)(40) + (40)² + 3(0)²))
σ' = (√(7921 + 3560 + 1600 + 0))
σ' = (√13081)
σ' ≈ 114.41 MPa
Now, we can calculate the factor of safety (n):
n = Sy/σ'
n = 295 MPa / 114.41 MPa
n ≈ 2.58
Therefore, the factor of safety is approximately 2.58.

what is settling velocity? what factors influence settling velocity? does settling velocity affect the dissolved load?
Answers
A particle's settling velocity is the rate at which it travels through a still fluid. The specific gravity of the particles, their size, and their shape all have an impact on settling velocity.
A particle in still air will gravitationally settle and reach its terminal velocity fairly quickly. A particle's terminal velocity in a still fluid is referred to as the settling velocity (also known as the "sedimentation velocity"). Understanding variations in the hydraulic regime and interactions between sediment and fluid in the surf zone depends heavily on the particle settling velocity at the foreshore region. In contrast to sedimentation, which is the end product of the settling process, settling is the movement of suspended particles through the liquid. Sedimentation in geology is the process by which sediments are deposited and sedimentary rock is created. The process of sedimentation involves allowing particles suspended in water to separate under the influence of gravity.

Answers
The values of D60 and D30 for the given soil are approximately 1.147 mm.
To calculate D60 and D30 for a soil using the given values of Cu, CC, and D10, we can use the following equations:
D60 = D10 * (Cu/CC)^(1/2)
D30 = D10 * (Cu/CC)^(1/2)
Given:
Cu = 5.4
CC = 1.46
D10 = 0.31 mm
Let's calculate D60 and D30 using these equations:
D60 = 0.31 * (5.4/1.46)^(1/2)
D60 ≈ 0.31 * 3.698
D60 ≈ 1.147 mm
D30 = 0.31 * (5.4/1.46)^(1/2)
D30 ≈ 0.31 * 3.698
D30 ≈ 1.147 mm

Consider a 2.4-kW hooded electric open burner in an area where the unit costs of electricity and natural gas are $0.10/kWh and $1.20/therm (1 therm = 105,500 kJ), respectively. The efficiency of open burners can be taken to be 73 percent for electric burners and 38 percent for gas burners. Determine the rate of energy consumption and the unit cost of utilized energy for both electric and gas burners.
Answers
Answer:
1.75 kW
$0.137 kWh
4.61 kW
$3.16 therm
Explanation:
Utilized power input of the burner is
P(ui) = total power input * efficiency
P(ui) = 2400 W * 0.73
P(ui) = 1752 W or 1.75 kW
Unit cost of utilized energy is
C(ui) = Unit cost of electricity/efficiency
C(ui) = $0.1 / 0.73 kWh
C(ui) = $0.137 kWh
Power input to the gas burner is
P(gi) = Utilized power input of the burner / efficiency of the burner
P(gi) = 1.75 / 0.38
P(gi) = 4.61 kW
Unit cost of utilized energy is
C(gi) = Unit cost of gas /efficiency
C(gi) = $1.2 / 0.38 kWh

A winery in Paso Robles uses three identical 25 m3 lagoons in series to remove BOD from their 12.3 m3/d waste stream. If the BOD degradation rate coefficient in each lagoon is 1.2/day, what is their total percentage of BOD reduction
Answers
Overall BOD reduction = (BOD reduction in lagoon 1) * (BOD reduction in lagoon 2) * (BOD reduction in lagoon 3)
Now we can substitute the values and calculate the overall BOD reduction.
To calculate the total percentage of BOD reduction in the three lagoons, we need to determine the BOD reduction in each lagoon and then calculate the overall reduction.
Given:
Number of lagoons (n) = 3
Volume of each lagoon (V) = 25 m^3
Waste stream flow rate (Q) = 12.3 m^3/d
BOD degradation rate coefficient (k) = 1.2/day
The BOD reduction in each lagoon can be calculated using the formula:
BOD reduction = (1 - e^(-kV)) * 100
Applying this formula to each lagoon, we get:
BOD reduction in lagoon 1 = (1 - e^(-1.2 * 25)) * 100
BOD reduction in lagoon 2 = (1 - e^(-1.2 * 25)) * 100
BOD reduction in lagoon 3 = (1 - e^(-1.2 * 25)) * 100

volume of alcohol \(V_0\) = 500
Temperature change ΔT = (30° - 5°)C

\(\beta_{ alcohol }= 1.12 \times 10^{-4} / ^0C\)
The increase in volume ΔV = \(\alpha \times V_o \times \Delta T\)

Using the formula XC=1/(2πfC) in your answer, how would a capacitor influence a simple DC series circuit?
Answers
The capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.
What is a DC series circuit?A DC series circuit can be defined as a type of circuit in which all of its resistive components are connected end to end, so as to form a single path for the flow of current.
This ultimately implies that, the same amount of current flows through a direct current (DC) series circuit.
The capacitive reactance of a DC series circuit.Mathematically, the capacitive reactance of a DC series circuit is given by this formula:
\(X_C = \frac{1}{2\pi fC}\)
Where:
is the capacitive reactance.f is the frequency.C is the capacitance.From the above formula, we can deduce that the capacitive reactance of a DC series circuit is inversely proportional to both frequency and capacitance. Thus, the capacitive reactance of a DC series circuit increases when its capacitance decreases and vice-versa.
In conclusion, a capacitor would influence a simple DC series circuit by blocking the flow of direct current (DC) through it.

Assembly is essentially binary code written in a way that people can read it. The assembler then converts the assembly code, line by line, to the corresponding bit code.
What is the difference between Assembly and binary?In essence, assembly is binary code that has been translated into a language that people can read. Then, the assembler takes the assembly code and converts it bit-by-bit to the corresponding bit code.Imagine that there is a table with a line for each potential assembly statement. The statement itself is next on each line, followed by the corresponding bits that the computer can understand on the right.Even so, assemblers also have supplementary features like macros and other features, but the aforementioned functionality is their primary functionality.Binary is just a numbering scheme to programmers. For instance, base2 contains some 0s and 1s. These binary numbers are used by all computers. They interpret the instructions as a list of these numbers. They are not affected by the human-generated code, which is typically produced using a high-level programming language like Python, Java, and others.It is obvious that machine instructions in computers are not really human-readable - most people cannot determine the operational difference between 100010001... and 010001000... by simply looking at a binary or hex representation of the instruction bytes. Simply put, these instructions are machine codes.For instance, in the x86-16 architecture, the following instruction is used as the machine code for loading a value into a register: With a 2-bit addressing mode field and a 3-bit base register, the formula 8B 0E 34 12 denotes mov r16, r/m16, and which register the destination is (in this case, CX). For the avoidance of doubt, the Machine Code is represented using HEX code. Actually, it is simple to translate it to binary, and you have already mentioned that it is "10001011000011100011010000010010. Just like a string of ASCII 0 and 1 but more condensed, HEX is a text serialization format for binary numbers.Such binray/HEX instructions are readable by humans thanks to assembly, which is a higher level programming language than machine code.
