Which three items below should a driver be able to identify under the hood of a car?

Answer:

no it has to be removed

Explanation:

It is completely inappropriate to mention that the drum brakes are usually designed so that the condition of the lining can be checked even if the drum has not been removed. Therefore, the statement given above is false.

Drum brakes can be referred to or considered as the types of brakes that are useful in application of brakes to an object, such as wheels, in motion. To understand better, it can be stated that the system of braking under drum brakes is completely in contrast to that of disc brakes.

Drum brakes have a hydraulic pressure, which means that if the condition of lining is to be checked, removal of drums becomes essential. If the drums are not removed, correction or alignment of wheels cannot be performed.

Therefore, the significance regarding drum brakes has been aforementioned, and the statement given above with respect to their removal also holds false.

The conductor size, fuse, or circuit breaker size, and overload size are generally determined using the National Electrical Code (NEC).

National Electrical Code is a guidebook, which is a national standard published by the National Fire Protection Association (NFPA), that provides guidelines for the safe installation of electrical wiring and equipment in homes, buildings, and other facilities.

The NEC provides guidelines for wire ampacity, overcurrent protection, and maximum circuit length, among other things. The conductor size is determined by the load current, the maximum circuit length, and the conductor temperature rating.

The maximum circuit length is determined by the voltage drop, the load current, and the conductor size.Fuse and circuit breaker sizes are determined based on the current-carrying capacity of the conductor. They must be properly sized to protect the conductor from overcurrent, but not so small that they trip unnecessarily.The overload size is determined based on the load current.

Overload protection is a type of overcurrent protection that protects equipment from overheating and burning out due to excessive current. It is usually provided by thermal overload relays or electronic overload relays, which detect excessive current and disconnect the power source to the equipment.

Assuming we have to find out the compression ratio of the engine

Given information

Cubic capacity of the engine, V = 245 cc

Clearance volume, V_c = 27.2 cc

over square-ratio = 1.1

thus,

D/L = 1.1

where,

D is the bore

L is the stroke

Now,

Volume of the engine V =\(\frac{\pi}{4} D^2L\)

plugging values we get

245 = \(\frac{\pi}{4} D^3/1.1\)

Solving we get D =7 cm

therefore,  L= 7/1.1 =6.36 cm

Now,

the compression ratio is given as:

r =(V+V_c)/V_c

on substituting the values, we get

r = (245+27.2)/27.2 =10.007

Hence, Compression ratio = 10.007

The number of revolutions through which the wheel turns during this interval is 50 + 3π / r.

To solve this problem, we can use the formula for uniform acceleration:

ω₂ - ω₁ = αt

where ω₁ and ω₂ are the initial and final angular velocities, α is the angular acceleration, and t is the time interval.

We know that ω₁ = 300 rev/min, ω₂ = 900 rev/min, and t = 6 seconds. We need to find α to use the above formula.

We can use the formula for angular acceleration:

α = τ / I

where τ is the torque applied and I is the moment of inertia of the flywheel.

We don't have the moment of inertia, but we can use the fact that the acceleration is uniform to relate α to the linear acceleration a and the radius r of the flywheel:

a = αr

We can also use the formula for linear acceleration:

a = F / m

where F is the force applied and m is the mass of the flywheel.

We don't have the mass, but we can use the fact that the torque is related to the force by:

τ = Fr

where r is the radius of the flywheel.

Putting all of these equations together, we can solve for α:

α = τ / I = Fr / Ir = (a / r) / (ω₂ - ω₁) = (2π / 60) (900 - 300) / (6 / 60) / r
  = 2π (600 / 360) / r
  = π / (3r)

Now we can use the formula for angular displacement:

θ = ω₁t + (1/2)αt²

to find the number of revolutions N:

N = θ / (2π) = [(300)(6) + (1/2)(π/3r)(6)²] / (2π)

Programmed latching circuits are retentive. This means that if power is interrupted the output will remain in its previous state when power is returned. This is one of the features that makes these circuits so useful and popular in many different applications.

Programmed latching circuits are digital circuits that are designed to "latch" onto an output state when a certain input signal is received. Once the circuit latches onto an output state, it will remain in that state until it receives another input signal to change it.  This makes these circuits useful in applications where it is necessary to control the state of a device with a single input signal.

These circuits are especially useful in applications where it is important to maintain a specific output state, even if power is lost or interrupted .Latching circuits are also used in many different types of safety systems. For example, a latching circuit might be used to control an emergency stop button in a machine shop. If the button is pressed, the latching circuit will turn off the power to the machine, and the machine will stop. The latching circuit will then remain in the "off" state until it is manually reset by an operator.

Plate boundaries are significant points where the Earth's tectonic plates interact with one another. There are three distinct types of plate boundaries: convergent, transform, and divergent.

At convergent boundaries, two plates are moving towards each other and either collide or press against each other. If two oceanic plates meet, one will be subducted under the other, leading to the formation of an oceanic-oceanic boundary. If an oceanic plate and a continental plate collide, the oceanic plate will be subducted under the continent, creating an oceanic-continental boundary. If two continental plates collide, they will push against each other, forming a mountainous region and an resulting in a continental-continental boundary.

Transform boundaries occur where two plates are sliding past each other horizontally without the creation or destruction of crust. These boundaries are known for their large faults and earthquakes, such as the famous San Andreas Fault in California.

At divergent boundaries, two plates are moving away from each other, leading to the creation of new crust and the expansion of either oceanic or continental plates. This type of boundary can be found at the mid-Atlantic ridge, where new oceanic crust is formed as the North American and Eurasian plates move apart.

In summary, understanding the characteristics of plate boundaries is important in comprehending the processes that shape our planet. These boundaries play a crucial role in shaping the Earth's surface and further knowledge of them contributes to a deeper understanding of the Earth's geology and geophysics.

Answer:

Both Tech A and Tech B are correct. The oxygen sensor is indeed a part of the feedback system for the engine management system. The oxygen sensor measures the amount of oxygen in the exhaust gas and sends this information to the powertrain control module (PCM). Based on this information, the PCM can adjust the fuel mixture to ensure that it is optimally balanced for the current driving conditions.

Long-term fuel trims refer to the adjustments that the PCM makes to the fuel mixture over an extended period of time. Positive long-term fuel trims indicate that the PCM is leaning out the fuel mixture by reducing the amount of fuel injected into the engine. This is typically done in order to compensate for a condition that is causing the engine to run rich (too much fuel in the mixture).

The initial enthalpy and the entropy of the saturated water can be found out from the table of A-12E

i.e.   \($h_1= 101 \ \text{Btu/lbm}$\)

       \($s_1 = 0.22717 \text{ Btu/lbmR}$\)

Since the process mentioned above is an adiabatic compression process, the entropy will remain constant throughout the process. Therefore, we take the value of entropy and the final pressure using the table with few interpolations and also approximations to find the final enthalpy. It is given by :

       \($h_2= 116.09 \text{ Btu/lbm}$\)

So the work input from the energy balance equation :

       \($\dot{W} + \dot{m}h_1 = \dot{m}h_2$\)

          \($w=h_2 - h_1$\)

              = 116.09 - 101

              = 15.09

Therefore, \($w= 15.09 \text{ Btu/lbm}$\)
