The steel bracket is used to connect the ends of two cables. if the allowable normal stress for the steel is sallow = 30 ksi, determine the largest tensile force p that can be applied to the cables. assume the bracket is a rod having a diameter of 1.5 in.
The largest tensile force that can be applied to the cables given a rod with diameter 1.5 is 2013.15lb
The static equilibrium is given as:
F = P (Normal force)
Formula for moment at section
M = P(4 + 1.5/2)
= 4.75p
Solve for the cross sectional area
Area = [tex]\frac{\pi d^{2} }{4}[/tex]
d = 1.5
[tex]\frac{\pi *1.5^{2} }{4}[/tex]
= 1.767 inches²
Solve for inertia
[tex]\frac{\pi *0.75^4}{4}[/tex]
= 0.2485inches⁴
Solve for the tensile force from here
[tex]\frac{F}{A} +\frac{Mc}{I}[/tex]
30x10³ = [tex]\frac{P}{1.767} +\frac{4.75p*0.75}{0.2485} \\\\[/tex]
30000 = 14.902 p
divide through by 14.902

A traffic flow has density 61 veh/km when the speed is 59 veh/hr. If a flow has a jam density of 122 veh/km, what is the maximum flow in veh/hr (in whole number)? Use Greenshield Model.
Since this traffic flow has a jam density of 122 veh/km, the maximum flow is equal to 3,599 veh/hr.
Given the following data:
Density = 61 veh/km.Speed = 59 km/hr.Jam density = 122 veh/km.How to calculate the maximum flow.According to Greenshield Model, maximum flow is given by this formula:
[tex]q_{max}=\frac{V_f \times K_i}{4}[/tex]
Where:
[tex]V_f[/tex] is the free flow speed.[tex]K_i[/tex] is the Jam density.In order to calculate the free flow speed, we would use this formula:
[tex]V_f =2 V\\\\V_f =2\times 59\\\\V_f=118\;km/hr[/tex]
Substituting the parameters into the model, we have:
[tex]q_{max}=\frac{118 \times 122}{4}\\\\q_{max}=\frac{14396}{4}[/tex]
Max flow = 3,599 veh/hr.

Might a synchronous motor equally well be called a synchronous inductor
In Engineering, a synchronous motor is sometimes referred to as synchronous capacitor but not a synchronous inductor.
What is a synchronous motor?A synchronous motor can be defined as an alternating current (AC) electric motor in which the rotation speed of the shaft is directly proportional to the frequency of the supply current, especially at steady state.
Basically, a synchronous motor is sometimes referred to as a synchronous capacitor because it can be used to correct the power factor (PF) of a lagging load such as an induction motor.
However, a synchronous motor cannot be called a synchronous inductor because the rotation speed of the shaft is not proportional to the synchronous speed of the motor. Thus, they are called an synchronous motor.

Based on your understanding of color’s relationship to wavelength, identify the approximate wavelength of light (nm) emitted by strontium when it was burned in Part C. (No quantitative data was collected for this; you are giving an approximate value only, based on what you observed. ) Strontium emission = _________________nm
Explain your reasoning in full, making sure to cite specific data and observations to support your answer.
Q. 5 What would you conclude about chloride based on your results in the flame tests in Part C?
Q. 6 Place the metal solutions you tested in order of increasing energy based on the colors observed in the flame test; i. E. , A < B < C
The approximate emmission of Crimson is 620 to 700 nm
We would have to identify the wavelength that are emitted by the strontium.
In the strontium test, the observations would be based on the flames that are crimson red.
In the color wheel, the color with the highest wavelength is red at 620 to 700 mm.
3. The original color that is present in the test comes from when metal salt is heated. This usually causes its outer electrons to be excited, falling back to different energy wavelength in the spectrum.
Higher wavelength = loosely bound electron in the outer shell so that less energy is required.
The metals are red when they are burnt. The red color is the one with the highest wave length.

A strain gauge is used to measure the strain on a vibrating beam which can vibrate up to a maximum frequency of 60 Hz. The strain gauge analog signal is converted in to a digital signal via an Analog to Digital Converter (ADC) in order to store the data on a computer hard drive. The engineer responsible for this measurement mistakenly selects a sampling frequency of 90 Hz for the ADC. (a) Determine the alias frequency due to the small sampling frequency. (b) Propose a sampling frequency that will not result into aliasing of the analog signal (make sure to provide your rationale for selecting this frequency)
The aliased frequency that is due to small sampling frequency is 675 Hz.
The proposed sampling frequency is 2f = 120
How to solve for the aliased frequencyThe signal frequency that is given in the question is 60Hz
The sampling frequency is 90Hz
a. Using Nyquist frequency,
fn = 0.5*90Hz = 45Hz
The aliased frequency = |n*fn - fs|
aliased frequency = |n*fn - fs|
We have n >= 1/Fs = 17ms
Then the aliased frequency is = 17 x 45 - 90
= 675 Hz
b) The Nyquist sampling theoremIn order to avoid aliasing the sampling frequency, this has to be at least two times the highest frequency.
Therefore Fs =
2xF = 120Hz

A platinum resistance temperature detector has a resistance of 100.00 V at 0°C, 138.50 V at 100°C and 175.83 V at 200°C. What will be the nonlinearity error in °C at 100°C if the detector is assumed to have a linear relationship between 0 and 200°C?
Answer:
about 1.54 °C
Explanation:
The error will be the difference between the temperature interpreted from the resistance value and the actual temperature. The linear equation used to translate the resistance reading to temperature will be ...
T = (200 -0)/(175.83 -100.00)(R -100.00)
T ≈ 2.637479(R -100)
At the temperature of 100°C, the resistance value of 138.50 will be interpreted to be a temperature of ...
T = 2.637479(138.50 -100) ≈ 101.543°C
This represents an error of 1.543°C relative to the actual temperature.
