Wheels A and B have weights of 150 lb and 100 lb , respectively. Initially, wheel A rotates clockwise with a constant angular velocity of 100 / A rad s and wheel B is at rest. If A is brought into contact with B, determine the time required for both wheels to attain the same angular velocity. The coefficient of kinetic friction between the two wheels is 0.3 k and the radii of gyration of A and B about their respective centers of mass are 1 A k ft and 0.75 B k ft . Neglect the weight of link AC.
Answers
The image attached that is supposed to be attached to the question is shown in the first file below.
Answer:
t = 2.19 seconds
Explanation:
The free body diagram showing the center of mass A and B is attached in the second diagram below.
NOTE : that from the second diagram; Mass A and B do not have any acceleration
Taking the moment about wheel A:
\(\sum M_A = I_A \alpha _A\)
\(-f(r_A) = I_A \alpha _A ----- (1)\)
The equilibrium forces in the y-direction is 0
i.e
\(F_y = 0\)
So;
\(N +T sin 30^0 -W_A = 0 ----- (2)\)
The equilibrium forces in the x-direction is as follows:
\(\sum F_x = 0\)
\(Tcos 30^0 + f= 0 -----(3)\)
The kinetic friction f can be expressed as :
\(f = \mu _k N\)
From above equation (2) and equation (3);
\(N + [\dfrac{-f}{cos 30^0}]sin 30^0 -150 =0\)
\(N - \mu _k N \ tan 30^0 -150 =0\)
\(N = \dfrac{150}{1-0.3 \ tan 30^0}\)
N = 181.423 lb
Similarly; from equation(1)
\(\alpha_A = - \dfrac{f(r_A)}{I_A}\)
\(\alpha _A = \dfrac{-\mu_k N(r_A)}{I_A}\)
\(\alpha _A = \dfrac{-0.3*181.423*1.25}{\frac{150}{32.2}*I^2}\)
\(\alpha _A =-14.6045 \ rad/s^2\)
However; from the kinematics ; as moments are constant ; so is the angular acceleration is constant )
Thus;
\(\omega _A - \omega_o^A = \alpha_A t\)
\(\omega _A = \omega_o^A + \alpha_A t\)
\(\omega _A = 100 -14.6045 \ t ---- (4)\)
Let's take a look at wheel B now;
Taking the moment about wheel B from the equation of motion:
\(\sum M_B = I_B \alpha _B\)
\(f(r_B) = I_B \alpha _B\)
\(\mu_k N (r_B) = I_B \alpha_B\)
\(\mu_k N (r_B) = \dfrac{W_B}{g}* k^2_B \alpha_B\)
\(\alpha_B = \dfrac{0.3*181.423*1}{\frac{100}{32.2}*0.75^2}\)
\(\alpha = 31.1563 \ rad/s^2\)
Again; from the kinematics; as the moments are constant which lead to the angular accleration;
\(\omega _B = \omega _o^B + \alpha _B \ t\)
\(\omega _B =0 + 31.156 \ t-----(5)\)
From equation 4 and 5 which attain the same angular velocity; we have;
\(\omega^A = \omega^B\)
100 - 14.6045 t = 31.1563 t
100 = 31.1563 t + 14.6045 t
100 = 45.761 t
t = 100/45.761
t = 2.19 seconds

Answers
Answer: C
Both A and B are correct
Explanation:
Latent heat is the hidden heat.
Latent heat is the heat energy required to change one state of matter to another state of matter without change in temperature. For example, solid state to liquid state, or liquid state to gaseous state.
Thermometer can not detect the latent heat. That is why it is called hidden heat.
If Technician A says that latent heat is hidden heat and cannot be measured on a thermometer. And Technician B says that latent heat is hidden heat that is required for a change of state of matter, then we can therefore conclude that both Technician A and Technician B are correct.

#SPJ11
which type of mining creates the greatest environmental damage
Answers
Among various types of mining, open-pit mining is often considered to create the greatest environmental damage. Open-pit mining, also known as open-cast or open-cut mining, involves the extraction of minerals or ores from the Earth's surface by removing overlying soil and rock layers.
There are several reasons why open-pit mining is associated with significant environmental damage:
Large-Scale Excavation: Open-pit mining requires the excavation and removal of vast amounts of soil, rocks, and vegetation. This process leads to the destruction of natural habitats, deforestation, and loss of biodiversity in the affected areas. The removal of topsoil and vegetation can result in long-term soil erosion and degradation.
Alteration of Landforms: Open-pit mining alters the natural topography of the land, resulting in the creation of deep pits and spoil heaps. These altered landforms can disrupt the hydrological systems, leading to changes in water flow patterns, contamination of groundwater, and the loss of aquatic habitats. The accumulation of waste rock and tailings in spoil heaps can release harmful chemicals into the environment, polluting nearby water sources.
Air and Water Pollution: The extraction and processing of minerals in open-pit mining often involve the use of explosives, heavy machinery, and chemical reagents. These activities can release dust, particulate matter, and toxic substances into the air, contributing to air pollution. The runoff from mining sites can carry sediments, heavy metals, and chemicals into nearby water bodies, causing water pollution and affecting aquatic ecosystems.
Energy Consumption and Greenhouse Gas Emissions: Open-pit mining requires significant energy inputs for excavation, transportation, and processing of minerals. The extraction and use of fossil fuels in mining operations contribute to greenhouse gas emissions, exacerbating climate change and its associated environmental impacts.
While it is important to note that the environmental impact of mining can vary depending on various factors, including the specific mineral being extracted, the location, and the mining practices employed, open-pit mining is generally considered more destructive due to its extensive scale, alteration of landforms, habitat destruction, and potential for pollution. Sustainable mining practices, strict environmental regulations, and reclamation efforts are crucial in mitigating the environmental damage associated with mining operations.

An Otto cycle with air as the working fluid has a compression ratio of 8.2. Under cold air standard conditions, what is the thermal efficiency of this cycle?
Answers
Answer:
Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.
Explanation:
From Thermodynamics we remember that thermal efficiency of the ideal Otto cycle (\(\eta_{th}\)), dimensionless, is defined by the following formula:
\(\eta_{th} = 1-\frac{1}{r^{\gamma-1}}\) (Eq. 1)
Where:
\(r\) - Compression ratio, dimensionless.
\(\gamma\) - Specific heat ratio, dimensionless.
Please notice that specific heat ratio under cold air standard conditions is \(\gamma = 1.4\).
If we know that \(r = 8.2\) and \(\gamma = 1.4\), then thermal efficiency of the ideal Otto cycle is:
\(\eta_{th} = 1-\frac{1}{8.2^{1.4-1}}\)
\(\eta_{th} = 0.569\)
Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.
Briefly explain thermal expansion using the potential energy–versus–interatomic spacing curve.

what is the speed of a spur gear with 42 teeth driven by a pinion gear with 14 teeth turning 420 rpm?
Answers
The formula for calculating gear speed is: (rpm of the driving gear * number of teeth on the driving gear) / number of teeth on the driven gear.
What is the formula for calculating gear speed?To calculate the speed of the spur gear, we can use the gear ratio formula, which is gear ratio = number of teeth on driven gear (spur gear) / number of teeth on driving gear (pinion gear).
In this case, the gear ratio is 42/14 = 3.
Next, we can use the formula for gear speed, which is gear speed = pinion gear speed / gear ratio.
Since the pinion gear is turning at 420 rpm, the gear speed of the spur gear is:
gear speed = 420 rpm / 3 = 140 rpm.
Therefore, the speed of the spur gear with 42 teeth driven by a pinion gear with 14 teeth turning at 420 rpm is 140 rpm.

When the electricity is switched on, the electric magnets create powerful magnetic fields. Coils of wire are mounted around the shaft. As the shaft with the magnets rotates, the coils of wire are exposed to changing magnetic fields, and an electric current is generated in the wires.
Answer:
Explanation:
I am pretty sure it depends but most of the time I think they produce direct current/voltage.

John has just graduated from State University. He owes $35,000 in college loans, but he does not have a job yet. The college loan company has agreed to give John a break on a deferred-payment plan that works as follows. John will not have to repay his loan for 5 years. During this “grace period” the loan obligation will compound at 4% per year. For the next 5 years, a monthly payment will be required, and the interest rate will be 0.5% per month. What will be John’s monthly payment over the 60-month repayment period?
Answers
Answer:
The correct response is "821.88". A further explanation is given below.
Explanation:
According to the question,
The largest amount unresolved after five years would have been:
= \(35000\times (\frac{F}{P}, 4 \ percent,5 )\)
= \(35000\times 1.216 7\)
= \(42584.50\)
Now,
time (t) will be:
= \(5\times 12\)
= \(60 \ monthly \ payments\)
So, monthly payment will be:
= \(42582.85\times (\frac{A}{P}, 0.5 \ percent,60 )\)
= \(42584.50\times 0.0193\)
= \(821.88\)
technician a says that a broken magnet becomes two magnets. technician b says that there is a strong relationship between magnetism and electricity. which technician is correct?
Answers
Both Technicians are correct as a broken magnet becomes two magnets and there is a strong relationship between magnetism and electricity.
What is magnetism?Electric charges in motion create the natural force known as magnetism. Inside of a substance known as magnets, these movements can occasionally be microscopic. Other magnets can be attracted to or repelled from by magnets, or by the magnetic fields produced by moving electric charges, which can also alter the motion of other charged particles.
According to the HyperPhysics website at Georgia State University, a magnetic field causes particles to experience the Lorentz force. The amount of charge, the particle's velocity, and the intensity of the magnetic field all affect the force that an electrically charged particle experiences in a magnetic field. The strange behavior of the Lorentz force is that it makes particles move at an angle to their initial motion.

Construct a context free grammar which generates the language {a^i b^j c^k | i != j ∨ j != k}
Answers
A context-free grammar can be constructed to generate the language {a^i b^j c^k | i != j ∨ j != k} by defining the rules for each condition separately.
To construct a context-free grammar for the given language, we need to consider the conditions i != j and j != k separately. For the first condition, we can define a rule that generates the string \(a^i b^j c^k\) where i > j. This can be done by using the production rules S → AB | AC and A → aA | ε, where B generates \(b^j c^k\) and C generates \(a^(i-j) b^j c^k\). Similarly, for the second condition, we can define a rule that generates the string \(a^i b^j c^k\)where j > k. This can be done by using the production rules S → AD | AE and D generates \(a^i b^j\)and E generates \(b^(j-k) c^k\).
Finally, we can combine these two rules to generate the language where either i != j or j != k. This can be done by using the production rule S → S1 | S2, where S1 generates the strings satisfying i > j and S2 generates the strings satisfying j > k.
