The elastic modulus for steel given in the table is 207 GPa, which is in reasonable agreement with this value E = 200.75 GPa
The elastic modulus is the slope in the linear elastic region:
б2 = б1 / Э2 - Э1
Since stress-strain curves for all of the metals/alloys pass through the o
rigin, and if we take σ1 = 0 then ε1 = 0. Determinations of σ2 and ε2 are possible by moving the cursor to some arbitrary point in the linear region of the curve and then reading corresponding values in the “Stress” and “Strain” windows that are located below the plot.
(a) A screenshot for the titanium alloy in the elastic region is shown below
Here the cursor point resides in the elastic region at a stress of 492.4 MPA (which is the value of σ2) at a strain of 0.0049 (which is the value of ε2). Thus, the elastic modulus is equal to
| 492.4-0
0.0049-0
E=100489.79 MPA
E=100.5 GPA
The elastic modulus for titanium given in the table is 107 GPA, which is in reasonably good agreement with this value.
(b) A screenshot for the tempered steel alloy in the elastic region is shown below
Here the cursor point resides in the elastic region at a stress of 916.7 MPA (which is the value of σ2) at a strain of 0.0045 (which is the value of ε2). Thus, the elastic modulus is equal to :
1916.7-0
0.0045 -0
E = 203711.11 MPA
E = 203.7 GPA
The elastic modulus for steel given in the table is 207 GPA, which is in good agreement with this value.
(c) A screenshot for the aluminum alloy in the elastic region is shown below.
Here the cursor point resides in the elastic region at a stress of 193.6 MPa (which is the value of σ2) at a strain of 0.0028 (which is the value of ε2). Thus, the elastic modulus is equal to:
193.6 – 0
0.0028 - 0
E = 69142.85 MPa
E = 69.14 GPa
The elastic modulus for aluminum given in the table is 69 GPa, which is in excellent agreement with this value.
(d) A screenshot for the carbon steel alloy in the elastic region is shown below
Here the cursor point resides in the elastic region at a stress of 160.6 MPa (which is the value of σ2) at a strain of 0.0008 (which is the value of ε2). Thus, the elastic modulus is equal to:
160.6 – 0
0.0008 - 0
E = 200750 MPa
E = 200.75 GPa

which nec article permits the disconnect switch for a large rooftop air conditioner to be mounted inside the unit?Step-by-step solution
Step 1 of 1
The compressor raises the energy level of the refrigerant.
Compressor raises the energy level of the refrigerant so that it can be condensed readily to a liquid. It serves as a pump to draw the expanded refrigerant gas from the evaporator. In addition, the compressor boosts the pressure of the gas and sends it to the condenser. The compression of the gas is necessary because this process adds the heat necessary to condense the gas to a liquid.
Article 440 permits the disconnect switch for a large rooftop air conditioner to be mounted inside the unit.
Disconnecting devices must be placed so that they are easily visible from and reachable from the cooling or heating equipment. Installing the disconnecting device on or inside the air-conditioning or refrigeration equipment is allowed. An HVAC system known as a packed rooftop unit, also known as an RTU, is a small unit that includes all the parts required to supply conditioned air. Packaged rooftop units are primarily used in small and large commercial applications. They are extremely well-liked by commercial and industrial properties.

When an exception is thrown by code in its try block, the JVM begins searching the try statement for a catch clause that can handle it and passes control of the program to ________.
A the statement that appears immediately after the catch block
B the first catch clause that can handle the exception
C the last catch clause that can handle the exception
D each catch clause that can handle the exception
When an exception is thrown by code in its try block, the JVM begins searching the try statement for a catch clause that can handle it and passes control of the program to the first catch clause that can handle the exception.
What is catch clause?In C#, a catch block is an optional section of code that is run after an exception is raised. The "catch" keyword is used in conjunction with the keywords "try" and "finally" to implement the catch block, which is a specific component of the exceptional handling construct and provides a method for implementing structured exception handling.
The code that is guarded and may result in an exception is included in a try block. It contains declarations that address exceptional situations and attempts to recover from such unforeseen circumstances.
The way to handle exceptions is formed by the catch block. The.NET run time may terminate the entire program if these issues are not resolved. For handling general or specific exceptions, use a catch block.

In the following gear train, Shaft A rotates at 200 rpm and shaft B rotates at 300 rpm in the directions indicated. Determine the speed of shaft C and its direction of rotation. N2 = 35; N3 = 25; N4 = 14; N5 = 46; No = 20; N, = 16
The speed of shaft C and its direction of rotation is 1160 rpm and C.C.W respectively.
What is speed?The rate of distance travel is referred to as speed. The SI units for measuring speed are meters per second (m/s), but other units such as miles per hour (mph), kilometers per hour (km/h), centimeters per year (cm/yr), and feet per second (ft/s) can also be used.
Due to the fact that distance is the only factor taken into account, it is a scalar quantity. Speed will ALWAYS be positive and cannot ever be negative. In a car, the speedometer displays the distance traveled; even when going backward, the speedometer still displays a positive speed. Speed is measured by how far you go in a given amount of time.

You are given a data stream that has been compressed to a length of 100,000 bits, and told that it is the result of running an "ideal" entropy coder on a sequence of data. You are also told that the original data consists of samples of a continuous waveform, quantized to 2 bits per sample. The probabilities of the uncompressed values are as follows: 00 1/2 01 3/8 10 1/16 11 1/16. What (approximately) was the length of the uncompressed signal?
The uncompressed values from given data is s = 10 p(s) = 1/16
compressed file uncompressed file
l=-(0.5 log 2 0.5)...= h bit/sample 2 bits sample
100,000 bits x bits
x bits ÷ 100000 bits = 2 bits/sample ÷ h bits sample
A data stream is the transmission of a series of coherent signals that have been digitally encoded to carry information. The sent symbols are often organized into a number of packets.
Data streaming is now commonplace. Any communication sent via the Internet is done so as a data stream. When speaking on a phone, the sound is transmitted as a data stream. Depending on the data format selected, Data Stream comprises several sorts of data. When determining the time of an event, attributes like the Timestamp attribute are helpful. An algorithmically encoded ID called "Subject ID" has been taken out of a cookie.
