Dual-Mode Hybrid

Explanation:

The type of hybrid vehicle propelled by only an electric motor and does not require a traditional transmission to drive the wheels is known as "DUAL-MODE HYBRID."

Dual-Mode Hybrid is a type of Hybrid Electric Vehicle (HEV) which contains a separate generator consisting of rechargeable batteries. The engine ensures the wheels and the generator are moved; thereby, the electric motor and the batteries are fully powered.

A good example is a Toyota Prius, where during driving conditions, only the electric motor drives the wheels, in which the batteries supply the car with power.

In a bipolar junction transistor, the current gain can be defined as the ratio of the collector current to the base current. It is generally denoted by \(hFE\)or \(β\).

When collector current (IC) is 10 mA and base current (IB) is 0.1 mA, then the current gain is given by the ratio of collector current to base current.

Therefore, the current gain (\(β\)) is given as:

\(β = IC/IBβ = 10/0.1β = 100\)

Thus, the current gain of the transistor is 100. This indicates that for every 1 mA of base current, the collector current is 100 mA. It is important to note that the current gain is not constant and varies with temperature, current, and other factors.

The current gain is an important parameter in transistor amplifiers as it determines the amplification factor of the circuit. An increase in the current gain leads to higher amplification and vice versa.

It is essential to choose a transistor with the appropriate current gain for a given application to ensure optimal performance.

Magnitude of normal stress component (σn) ≈ 13.7 kPa. Magnitude of shear stress component (τn) ≈ 7.4 kPa

To determine the magnitudes of the normal and shear stress components on an oblique plane, we can use the given stress components and the infinitesimal plane angle. The normal stress component is represented by σn, and the shear stress component is represented by τn.

Given:

σx = -25 kPa

σy = 15 kPa

τxy = 8 kPa

Infinitesimal plane angle = 34 degrees

To find the magnitudes of σn and τn, we can use the following formulas:

σn = (σx + σy) / 2 + (σx - σy) / 2 * cos(2θ) + τxy * sin(2θ)

τn = -(σx - σy) / 2 * sin(2θ) + τxy * cos(2θ)

Substituting the given values:

σn = (-25 + 15) / 2 + (-25 - 15) / 2 * cos(2 * 34°) + 8 * sin(2 * 34°)

τn = -(-25 - 15) / 2 * sin(2 * 34°) + 8 * cos(2 * 34°)

Calculating σn and τn using a calculator:

σn ≈ -13.7 kPa

τn ≈ -7.4 kPa

The magnitude of the normal stress component (σn) on the oblique plane is approximately 13.7 kPa, and the magnitude of the shear stress component (τn) is approximately 7.4 kPa.

The single addition to the automobile that gave the internal combustion engine the edge over steam and electric power was the development of the electric starter motor.

In the early days of automobiles, internal combustion engines required manual cranking to start. This process was physically demanding and potentially dangerous, as it involved hand-cranking a heavy flywheel to initiate the engine's combustion process. This limitation made internal combustion engines less convenient and less popular compared to steam and electric power, which offered easier and safer starting mechanisms.

However, with the invention of the electric starter motor, pioneered by Charles F. Kettering and introduced by Cadillac in 1912, the process of starting an internal combustion engine became significantly simpler. The electric starter motor enabled drivers to start their vehicles with just a turn of a key or a push of a button. This innovation eliminated the physical effort and risk associated with manual cranking, making internal combustion engines more accessible and user-friendly.

The convenience and reliability offered by the electric starter motor quickly made internal combustion engines the preferred choice for automobile manufacturers. The widespread adoption of this technology eventually led to the dominance of internal combustion engines in the automotive industry, as they became more efficient, powerful, and easier to start compared to steam and electric power.

Explanation:

In the steady state total volume going out will be equal to total volume coming in , and

total salt coming in = total salt going out

Total volume coming in per minute = 2000 + 2 x 10³ x 60

= 122000 L .

Total salt coming in per minute = 1200 x 2000 + 20  x 2 x 10³ x 60

= 2400000 + 2400000 mg

= 4800000 mg

volume of water going out per minute = 122000 L

Total salt going out  per minute = 4800000 mg

The break-even quantity is 94,000 fan blades. For a demand of 150,000 blades, Process B is recommended, resulting in cost savings of $280,000. To make an internal profit of $180,000, a demand of 235,000 blades is needed.

To calculate the cost savings and break-even quantity between the two processes, let's follow the steps:

Step 1: Calculate the break-even quantity:

The break-even quantity is the point at which the costs of both processes are equal.

Process A:

Fixed cost = $730,000

Variable cost per fan blade = $17

Process B:

Fixed cost = $1,200,000

Variable cost per fan blade = $12

To find the break-even quantity, we need to set the total costs of both processes equal to each other:

730,000 + 17Q = 1,200,000 + 12Q

Simplifying the equation:

5Q = 470,000

Q = 94,000

Therefore, the break-even quantity between the two processes is 94,000 fan blades (rounded to the nearest whole number).

Step 2: Calculate the total cost of each process for a demand of 150,000 blades:

Process A:

Fixed cost = $730,000

Variable cost per fan blade = $17

Total cost of Process A = Fixed cost + (Variable cost per fan blade * Demand)

                     = 730,000 + (17 * 150,000)

                     = 730,000 + 2,550,000

                     = $3,280,000

Process B:

Fixed cost = $1,200,000

Variable cost per fan blade = $12

Total cost of Process B = Fixed cost + (Variable cost per fan blade * Demand)

                     = 1,200,000 + (12 * 150,000)

                     = 1,200,000 + 1,800,000

                     = $3,000,000

Therefore, for a demand of 150,000 blades, Process B has a lower total cost compared to Process A.

Step 3: Calculate the cost savings:

Cost savings = Total cost of Process A - Total cost of Process B

            = 3,280,000 - 3,000,000

            = $280,000

The cost savings for choosing Process B over Process A is $280,000.

Step 4: Calculate the volume of demand needed to make an internal profit of $180,000:

To calculate the volume of demand needed to make a profit of $180,000, we subtract the profit from the total cost of the recommended process (Process B).

Profit = $180,000

Total cost of Process B = $3,000,000 (from Step 2)

Volume of demand = (Total cost of Process B - Profit) / Variable cost per fan blade

                = (3,000,000 - 180,000) / 12

                = 2,820,000 / 12

                = 235,000

Therefore, Samoset Fans, Inc. would need a volume of demand of 235,000 fan blades to make an internal profit of $180,000, assuming they installed Process B as recommended.

To summarize:

a. The break-even quantity between the two processes is 94,000 fan blades.

b. For a demand of 150,000 blades, Process B is recommended. Total cost of Process A is $3,280,000 and total cost of Process B is $3,000,000.

c. The cost savings for choosing Process B over Process A is $280,000.

d. Samoset Fans, Inc. needs a volume of demand of 235,000 fan blades to make an internal profit of $180,000 with Process B installed.
